摘要：This paper presents the impact of Distribution Generation (DG) on congestion, loss, Locational Marginal Pricing (LMP), and Social Surplus in the Optimum Power Flow (OPF) based restructured electricity market. The issue of perfect placement of DG to reduce congestion and also lower LMPs is formulated with the objective of social surplus maximization. In this work, the seed genetic algorithm method by using DC Optimal Power Flow (DCOPF) is proposed to calculate LMPs at all buses while maximizing social surplus or minimizing fuel cost. Different scenarios for LMP determination i.e. not considering losses, losses are considered but concentrated at reference bus, and losses are distributed at all buses have been examined. Linear bids are assumed for generators. Here, the load is considered as fixed i.e. inelastic. The impact of DG on loss, congestion, LMP, and social surplus has been presented in IEEE 14- Bus system.
