In energy network operation, some scholars have researched energy storage capacity planning in island power systems, with total cost reduction as the optimization objective [11]. The capacity of energy storage facility under different scenarios is the key to improve the resilience of the islanded microgrid to uncertainty [ 12 ].
Results verify that the multiple vir-tual power plants with a shared energy storage system interconnection system based on the sharing mechanism not only can achieve a win‐win situation between the VPPO and the SESS on an operation cost but also obtain the optimal allocation scheme and im-proves the operation eficiency of the VPPs. INTRODUCTION.
The operation model of a virtual power plant (VPP) that includes synchronous distributed generating units, combined heat and power unit, renewable sources, small pumped and thermal storage elements, and electric vehicles is described in the present research. The VPPs are involved in the day-ahead energy and regulation …
Electrical energy storage (EES) alternatives for storing energy in a grid scale are typically batteries and pumped-hydro storage (PHS). Batteries benefit from ever-decreasing capital costs [14] and will probably offer an affordable solution for storing energy for daily energy variations or provide ancillary services [15], [16], [17], [18].
In view of the problem that the energy storage power plant can not fully exert the power fluctuation of the distribution network when it operates with a single target, the operation …
