VPP2 is equipped with DG only, which has a weak regulation ability to follow loads. Shared energy storage system provides flexible adjustment capabilities during load peaks and valleys to reduce the cost of curtailment and reduces the operation cost by 25.91%. In addition to DG, VPP3 is only equipped with photovoltaics, whereas VPP4 is only
During discharge of the TES-CFPP system, the heat stored in the molten salt enters the turbine system, thereby generating more output power. As shown in Fig. 3, the DEA outlet feed water was partially diverted to MSH2 for heat exchange with the molten salt flowing from the hot tank (HT), and the cooled molten salt entered the cold tank (CT)
A novel approach for integrating energy storage as an evo-lutionary measure to overcome many of the challenges, which arise from increasing RES and balancing with thermal power is presented. Energy storage technologies such as Power to Fuel, Liquid Air Energy Storage and Batteries are investigated in conjunction with flexible power plants.
