Optimal placement of D-STATCOM and PV solar in distribution system using probabilistic load models

this paper proposes a hybrid analytical and metaheuristic optimization technique to find the proper locations and sizes for the distributed generator (DG) and Distribution Static Synchronous Compensator (D-STATCOM) in distribution networks to minimize the total losses and improve the voltage profile. The D-STATCOM and DGs are arranged in order to reduce line losses and improve the voltage profile of the system. For this goal, the important parameters of a bus are optimized by Particle Swarm Optimization (PSO) algorithm. probabilistic load model also is calculated using Monte Carlo Simulation (MCS) method. Effectiveness of modified method is tested in a real distribution system of south Kerman (DSSK).
