Multi-Objective Optimal Siting and Sizing of Distributed Generators and Shunt Capacitors Considering the Effect of Voltage-Dependent Nonlinear Load Models

Load modeling is essential to distribution system analysis, planning, and control. Therefore, in this work, effect of non-linear load models has been considered for the optimal site size DG SC allocation. A new efficient modified branch bus ordering-based forward-backward flow method applied solve problem radial system. Recently implemented several state-of-the-art evolutionary algorithms (EAs) are employed allocation problems it shown that performance multi-operator/multimethod better than other based on a single operator and/or algorithm. hybrid EA various operators such as GA, DE, PSO designed problems. Various technical objective functions (index active reactive power loss voltage deviation index) show impacts models. From simulation results, multi-objective. further weighted sum multi-objective technical, economic, environmental formulated find solution The gathered results demonstrate proposed methodology significantly minimizes cost energy supplied by grid, total operating cost, losses. Consequently, can be stated suggested considerable economic technological benefits may used address many optimization issues networks.
