Multi-Objective Optimal Placement and Sizing of Distribution Static Compensator in Radial Distribution Networks With Variable Residential, Commercial and Industrial Demands Considering Reliability

This article presents an optimal placement and sizing of distribution static compensator (DSTATCOM) in radial networks as multi-objective optimization with the objective power loss reduction, voltage profile improvement network reliability considering different variable demands using whale algorithm (WOA). The WOA is inspired by hunting behavior humpback whales. location size DSTATCOM are considered decision variables that determined WOA. Network defined energy not supplied (ENS) customers caused line outages. proposed method implemented on IEEE 33-bus Ahvaz 59-bus networks. investigated residential, commercial industrial loads, also effect incorporating evaluated loss, minimum ENS. simulation results show ENS declined improved determining loading conditions obtained demonstrate further reduces more customer demand met. decreases 21.60%, 30.71%, 22.03% for loads 26.86%, 31.94%, 24.39% 69-bus network, respectively compared to base Moreover, performance previous studies indicate superiority method.
