Reinforcement of the distribution grids to improve the hosting capacity of distributed generation: Multi-objective framework

Excessive penetration of renewable energy resources into the distribution grid without additional preventive measures has led to several operational problems. However, most strategies developed accommodate more units suffered from other Therefore, further efforts are needed address key vulnerabilities in addition maximizing hosting capacity. In this regard, study is devoted a new multi-objective formulation maximize capacity and minimize total losses while satisfying constraints transferred off-peak hours. The Multi-Objective Advanced Gray Wolf Optimization (MOAGWO) algorithm used as solution tool. proposed tested on IEEE-33-bus 69-bus medium voltage test systems. impacts storage systems, regulators, static var compensators objective functions identified using scenarios. results showed that optimal device type locations depend level DG penetration. Finally, comparison according two popular performance indices quality Pareto front obtained by MOAGWO was better than ones with heuristic methods.
