ABSTRACT=In order to solve the problems of environmental pollution and energy consumption, it has become an urgent task to develop clean and renewable energy to maintain the sustainable development of society. Therefore, distributed generation (DG) has attracted extensive attention of engineers. However, the output of DG is usually random and intermittent. When connected to different locations, different sizing and different distribution network, it will have varying degrees of impact on the safe and stable operation of the power system. When choosing the optimal DG access scheme, planners must consider the impact of sizing, type and location to ensure that the power grid operation is safer, stable, reliable and efficient. Therefore, this paper proposes an objective function considering power losses, voltage profile and pollution emission, which is solved by equilibrium optimizer (EO). Finally, the effectiveness of the proposed strategy is verified based on IEEE 33-bus distribution networks. The results show that the strategy can effectively improve the pollution emission of the system, effectively reduce the power losses of the system and improve the voltage profile.
