Abstract

In the framework of vigorous promotion of low-carbon power system growth as well as economic globalization, multi-resource penetration in active distribution networks has been advancing fiercely. In particular, distributed generation (DG) based on renewable energy is critical for active distribution network operation enhancement. To comprehensively analyze the accessing impact of DG in distribution networks from various parts, this paper establishes an optimal DG location and sizing planning model based on active power losses, voltage profile, pollution emissions, and the economics of DG costs as well as meteorological conditions. Subsequently, multi-objective particle swarm optimization (MOPSO) is applied to obtain the optimal Pareto front. Besides, for the sake of avoiding the influence of the subjective setting of the weight coefficient, the decision method based on a modified ideal point is applied to execute a Pareto front decision. Finally, simulation tests based on IEEE33 and IEEE69 nodes are designed. The experimental results show that MOPSO can achieve wider and more uniform Pareto front distribution. In the IEEE33 node test system, power loss, and voltage deviation decreased by 52.23%, and 38.89%, respectively, while taking the economy into account. In the IEEE69 test system, the three indexes decreased by 19.67%, and 58.96%, respectively.
