Optimal Allocation of Renewable Energy Sources in Reconfigurable Distribution Systems Including Variable Electricity Consumption

Abstract

Energy losses of distribution systems are affected by operational costs, where these losses are more than transmission system ones. Distributed generation (DG) placement in reconfigurable power networks is an efficient way to minimize energy losses. Due to the great effect of renewable energy sources on environmental sustainability, DG penetration in distribution systems is increasing. Demand fluctuations play an essential role in determining the amount of losses and optimal generation of DG units in reconfigurable distribution systems. However, load variability consideration in the DG allocation and reconfiguration problem raises the burden and computational time considerably. Consequently, the current paper poses an effective reconfiguration and DG allocation approach for loss reduction in the presence of variable loads. Numerical results evaluation shows the excellent performance of the proposed approach for the optimal placement of DG units in reconfigurable distribution systems with time-varying loads.
