Optimal Energy and Reserve Scheduling of Pumped-Storage Power Plants
This paper presents a mixed-integer model for the hourly energy and reserve scheduling of a price-taker and closed-loop pumped-storage hydropower plant operating in hydraulic short-circuit mode. The plant participates in the spot market and in the secondary regulation reserve market, taking into account the regulation energy due to
Impact of operational scheduling of pumped storage power plant considering excess energy and reduction of fuel cost on power
In recent years, a substantial amount of photovoltaic (PV) generations have been installed in power systems. However, the power output from the PV is random and intermittent in nature. As a result, the PV generation poses many challenges to system operation. PV generates electricity only in the daytime regardless of power demand. When the daytime
HYDRO POWER PLANTS OF THE HSE GROUP: GREEN
Our hydro power plants on the Drava, Soča and Sava rivers produced a total of 3,980 GWh of electricity in 2021.
