CHANGES IN BUILD 20240912:

• Added variable head for turbine and pump in PHS (considering variable height of the reservoirs).
• Added variable losses in penstock (turbine and/or pump)
• Added optimization of minimum power (%) of the turbine to be used primarily to supply the load.
• Added the possibility to consider the water tank or reservoir CAPEX (capacity x specific cost), in PHS systems.
• Added optimization of the water tank or upper reservoir in PHS.
• Added cost due to the starts of hydro turbine and of pump.
• Added variable O&M for turbine and for pump.
• Added the possibility to calculate the water tank or reservoir capacity as the maximum obtained in the simulation, with specific limits (in PHS systems).
