The moving average of the demand, operating reserve, variable generation and ESS product inflows and outflows over the time step load levels is assigned to active load levels (e.g., the mean value of the three hours is associated to the third hour in a trihourly time step). Duration -------- A description of the data included in the file ``oH_Data_Duration.csv`` follows: ========== ======== =================================================================== == Identifier Header Description ========== ======== =================================================================== == Load level Duration Duration of the load level. Load levels with duration 0 are ignored h ========== ======== =================================================================== == It is a simple way to use isolated snapshots or representative days or just the first three months instead of all the hours of a year to simplify the optimization problem. A load level duration of 0.25 h would be used for defining all the data in quarters of an hour. Period ------ A description of the data included in the file ``oH_Data_Period.csv`` follows: ============== ============ ===================== Identifier Header Description ============== ============ ===================== Scenario Weight Weight of each period ============== ============ ===================== This weight allows the definition of equivalent (representative) hours (e.g., hour 0 with a weight of 7 would represent the first hour of 7 equivalent days). Periods are not mathematically connected between them, i.e., no constraints link the operation at different periods. Scenario -------- A description of the data included in the file ``oH_Data_Scenario.csv`` follows: ============== ============== ============ =========================================== ==== Identifier Identifier Header Description ============== ============== ============ =========================================== ==== Period Scenario Probability Probability of each scenario in each period p.u. ============== ============== ============ =========================================== ==== For example, the scenarios can be used for obtaining the optimal participation of the H-VPP considering renewables uncertainty represented (windy/cloudy orcalm/sunny). The sum of the probabilities of all the scenarios of a period must be 1. Stage ----- A description of the data included in the file ``oH_Data_Stage.csv`` follows: ============== ============ ===================== Identifier Header Description ============== ============ ===================== Scenario Weight Weight of each stage ============== ============ ===================== This weight allows the definition of equivalent (representative) periods (e.g., one representative week with a weight of 52). Stages are not mathematically connected between them, i.e., no constraints link the operation at different stages. Adequacy reserve margin ----------------------- A description of the data included in the file ``oH_Data_ReserveMargin.csv`` follows: ============== ============= ====================================== Identifier Header Description ============== ============= ====================================== Scenario ReserveMargin Adequacy reserve margin for each area ============== ============= ====================================== This parameter is only used for system generation expansion, not for the system operation. Duration -------- A description of the data included in the file ``oH_Data_Duration.csv`` follows: ========== =================================================================== ======== Header Description ========== =================================================================== ======== LoadLevel Load level datetime Duration Duration of the load level. Load levels with duration 0 are ignored h Stage Assignment of the load level to a stage ========== =================================================================== ======== It is a simple way to use isolated snapshots or representative days or just the first three months instead of all the hours of a year to simplify the optimization problem. The stage duration as sum of the duration of all the load levels must be larger or equal than the shortest duration of any storage type or any outflows type (both given in the generation data) and multiple of it. Consecutive stages are not tied between them. Consequently, the objective function must be a bit lower. The initial storage of the ESSs is also fixed at the beginning and end of each stage. For example, the initial storage level is set for the hour 8736 in case of a single stage or for the hours 4368 and 4369 (end of the first stage and beginning of the second stage) in case of two stages, each with 4368 hours. Electricity demand ------------------ A description of the data included in the file ``oH_Data_Demand.csv`` follows: ========== ============== ========== ====== ============================================ == Identifier Identifier Identifier Header Description ========== ============== ========== ====== ============================================ == Period Scenario Load level Node Power demand of the node for each load level MW ========== ============== ========== ====== ============================================ == The electricity demand can be negative for the (transmission) nodes where there is (renewable) generation in lower voltage levels. This negative demand is equivalent to generate that power amount in this node. Internally, all the values below if positive demand (or above if negative demand) 2.5e-5 times the maximum system demand of each area will be converted into 0 by the model. System inertia -------------- A description of the data included in the files ``oH_Data_Inertia.csv`` follows: ========== ============== ========== ====== ================================================ == Identifier Identifier Identifier Header Description ========== ============== ========== ====== ================================================ == Period Scenario Load level Area System inertia of the area for each load level s ========== ============== ========== ====== ================================================ == Given that the system inertia depends on the area, it can be sensible to assign an area as a country, for example. The system inertia can be used for imposing a minimum synchronous power and, consequently, force the commitment of at least some rotating units. Internally, all the values below 2.5e-5 times the maximum system electricity demand of each area will be converted into 0 by the model. Upward and downward operating reserves -------------------------------------- A description of the data included in the files ``oH_Data_OperatingReserveUp.csv`` and ``oH_Data_OperatingReserveDown.csv`` follows: ========== ============== ========== ====== =================================================================== == Identifier Identifier Identifier Header Description ========== ============== ========== ====== =================================================================== == Period Scenario Load level Area Upward/downward operating reserves of the area for each load level MW ========== ============== ========== ====== =================================================================== == Given that the operating reserves depend on the area, it can be sensible to assign an area as a country, for example. These operating reserves must include Automatic Frequency Restoration Reserves (aFRR), Manual Frequency Restoration Reserves (mFRR) and Replacement Reserves (RR) for electricity balancing from ENTSO-E. Internally, all the values below 2.5e-5 times the maximum system demand of each area will be converted into 0 by the model.

RetirementUp Upper bound of retirement decision p.u. ==================== ================================================================================================================================ =================================== Daily *storage type* means that the ESS inventory is assessed every time step, for weekly storage type it is assessed at the end of every day, and monthly/yearly storage type is assessed at the end of every week. *Outflows type* represents the interval when the energy extracted from the storage must be satisfied (for daily outflows type at the end of every day, i.e., the sum of the energy consumed must be equal to the sum of outflows for every day). *Energy type* represents the interval when the minimum or maximum energy to be produced by a unit must be satisfied (for daily energy type at the end of every day, i.e., the sum of the energy generated by the unit must be lower/greater to the sum of max/min energy for every day). The *storage cycle* is the minimum between the inventory assessment period (defined by the storage type), the outflows period (defined by the outflows type), and the energy period (defined by the energy type) (only if outflows or energy power values have been introduced). It can be one time step, one day, and one week. The ESS inventory level at the end of a larger storage cycle is fixed to its initial value, i.e., the inventory of a daily storage type (evaluated on a time step basis) is fixed at the end of the week, the inventory of weekly/monthly storage is fixed at the end of the year, only if the initial inventory lies between the storage limits. The initial storage of the ESSs is also fixed at the beginning and end of each stage, only if the initial inventory lies between the storage limits. For example, the initial storage level is set for the hour 8736 in case of a single stage or for the hours 4368 and 4369 (end of the first stage and beginning of the second stage) in case of two stages, each with 4368 hours. A generator with operation cost (sum of the fuel and emission cost, excluding O&M cost) > 0 is considered a non-renewable unit. If the unit has no operation cost and its maximum storage = 0, it is considered a renewable unit. If its maximum storage is > 0, with or without operation cost, is considered an ESS. Must-run non-renewable units are always committed, i.e., their commitment decision is equal to 1. All must-run units are forced to produce at least their minimum output. If unit availability is left 0 or empty is changed to 1. For declaring a unit non contributing to system adequacy reserve margin, put the availability equal to a very small number. EFOR is used to reduce the maximum and minimum power of the unit. For hydro units it can be used to reduce their maximum power by the water head effect. It does not reduce the maximum charge. Those generators or ESS with fixed cost > 0 are considered candidate and can be installed or not. Maximum and minimum storage is considered proportional to the invested capacity for the candidate ESS units if StorageInvestment is activated. If lower and upper bounds of investment/retirement decisions are very close (with a difference < 1e-3) to 0 or 1 are converted into 0 and 1. Variable maximum and minimum generation --------------------------------------- A description of the data included in the files ``oH_Data_VariableMaxGeneration.csv`` and ``oH_Data_VariableMinGeneration.csv`` follows: ========== ============== ========== ========= ============================================================ == Identifier Identifier Identifier Header Description ========== ============== ========== ========= ============================================================ == Period Scenario Load level Generator Maximum (minimum) power generation of the unit by load level MW ========== ============== ========== ========= ============================================================ == This information can be used for considering scheduled outages or weather-dependent operating capacity. To force a generator to produce 0 a lower value (e.g., 0.1 MW) strictly > 0, but not 0 (in which case the value will be ignored), must be introduced. This is needed to limit the solar production at night, for example. It can be used also for upper-bounding and/or lower-bounding the output of any generator (e.g., run-of-the-river hydro, wind). Internally, all the values below 2.5e-5 times the maximum system demand of each area will be converted into 0 by the model. Variable maximum and minimum consumption ---------------------------------------- A description of the data included in the files ``oH_Data_VariableMaxConsumption.csv`` and ``oH_Data_VariableMinConsumption.csv`` follows: ========== ============== ========== ========= ============================================================= == Identifier Identifier Identifier Header Description ========== ============== ========== ========= ============================================================= == Period Scenario Load level Generator Maximum (minimum) power consumption of the unit by load level MW ========== ============== ========== ========= ============================================================= == To force a ESS to consume 0 a lower value (e.g., 0.1 MW) strictly > 0, but not 0 (in which case the value will be ignored), must be introduced. It can be used also for upper-bounding and/or lower-bounding the consumption of any ESS (e.g., pumped-hydro storage, battery). Internally, all the values below 2.5e-5 times the maximum system demand of each area will be converted into 0 by the model. Variable fuel cost ------------------ A description of the data included in the file ``oH_Data_VariableFuelCost.csv`` follows: ========== ============== ========== ========= ============================= ====== Identifier Identifier Identifier Header Description ========== ============== ========== ========= ============================= ====== Period Scenario Load level Generator Variable fuel cost €/Mcal ========== ============== ========== ========= ============================= ====== All the generators must be defined as columns of these files. Internally, all the values below 1e-4 will be converted into 0 by the model. Fuel cost affects the linear and constant terms of the heat rate, expressed in Mcal/MWh and Mcal/h respectively. Energy inflows -------------- A description of the data included in the file ``oH_Data_EnergyInflows.csv`` follows: ========== ============== ========== ========= ============================= ===== Identifier Identifier Identifier Header Description ========== ============== ========== ========= ============================= ===== Period Scenario Load level Generator Energy inflows by load level MWh/h ========== ============== ========== ========= ============================= ===== All the generators must be defined as columns of these files. If you have daily energy inflows data just input the daily amount at the first hour of every day if the ESS have daily or weekly storage capacity. Internally, all the values below 2.5e-5 times the maximum system demand of each area will be converted into 0 by the model. Energy inflows are considered proportional to the invested capacity for the candidate ESS units if StorageInvestment is activated. Energy outflows --------------- A description of the data included in the file ``oH_Data_EnergyOutflows.csv`` follows: ========== ============== ========== ========= ============================= ===== Identifier Identifier Identifier Header Description ========== ============== ========== ========= ============================= ===== Period Scenario Load level Generator Energy outflows by load level MWh/h ========== ============== ========== ========= ============================= ===== All the generators must be defined as columns of these files. These energy outflows can be used to represent the energy extracted from an ESS to produce H2 from electrolyzers, to move EV or as hydro outflows for irrigation. The use of these outflows is incompatible with the charge of the ESS within the same time step (as the discharge of a battery is incompatible with the charge in the same hour). If you have daily/weekly/monthly/yearly outflows data, you can just input the daily/weekly/monthly/yearly amount at the first hour of every day/week/month/year. Internally, all the values below 2.5e-5 times the maximum system demand of each area will be converted into 0 by the model. Variable maximum and minimum storage ------------------------------------ A description of the data included in the files ``oH_Data_VariableMaxStorage.csv`` and ``oH_Data_VariableMinStorage.csv`` follows: ========== ============== ========== ========= ==================================================== === Identifier Identifier Identifier Header Description ========== ============== ========== ========= ==================================================== === Period Scenario Load level Generator Maximum (minimum) storage of the ESS by load level GWh ========== ============== ========== ========= ==================================================== === All the generators must be defined as columns of these files.

If there is no data for TTCBck, i.e., TTCBck is left empty or is equal to 0, it is substituted by the TTC in the code. Internally, all the TTC and TTCBck values below 2.5e-5 times the maximum system demand of each area will be converted into 0 by the model. Reactance can take a negative value as a result of the approximation of three-winding transformers.
