This determines the decision variables in the real-time stage: the power output of the CA-WT, the amount of power exchanged with the real-time market, and the DR power reduction. It should be noted that in this study, the DR program is only allowed to reduce power consumption.
The principle behind the operation of pumped storage power plants is both simple and ingenious. Their special feature: They are an energy store and a hydroelectric power plant in one. If there is a surplus of power in the grid, the pumped storage power station switches to pumping mode – an electric motor drives the pump turbines, which pumps

In 1963, the Liberian government received a loan from the World Bank to develop a US$24.3 million hydro electric project. Construction of the facility began in 1964 by the Monrovia Power Authority using Raymond Concrete Pile Company as the contractor and Stanley Consultants as the project managers. In 1966, the power company completed the initial phase of the dam and began generating electricity. The project was finished in 1967 and named the T. J. R. Faulkner W.F. W
Greater power plant flexibility and energy storage are viewed as key solutions to maintaining grid stability [2], [3], [7]. Current baseload thermal power plants have limited ability to modulate power output. The inflexibility is due largely to thermal cycling which can.
