Stochastic Flexible Power System Expansion Planning, Based on the Demand Response Considering Consumption and Generation Uncertainties

This paper presents the generation and transmission expansion planning (GTEP) considering switched capacitive banks (SCBs) allocation in power system, including demand response program (DRP). scheme is based on system flexibility. The objective function of minimizes expected cost that equaled to summation total construction costs SCBs, units (GUs) lines (TLs), operating GUs. It concerned with AC flow constraints, planning-operation model mentioned elements, DRP operation formulation, flexibility limits network. In following, scenario-based stochastic programming used uncertainty parameters, such as load renewable wind farms. Then, hybrid evolutionary algorithm, combination crow search algorithm grey wolf optimizer, determine optimal point approximate unique solution. Finally, applied networks, numerical results confirm capabilities proposed simultaneously improving flexibility, operation, economic situation network, so achieves solution a shorter computation time, compared non-hybrid algorithms. has low standard deviation about 92% final response. lines, sources, capacitor banks, together succeeded energy loss voltage by 30–36% 25–30%, those studies.
