The increasing number and scale of

The increasing number and scale of MGs have certain effects on therelevant parameters of internal nodes such as the node voltage increaseor decrease, reactive power fluctuation, etc., when they are connectedto the distribution network. At the same time, how to reasonably reducethe wind and light curtailment within the MG is also a hot issue in thefield of power system dispatching. In this paper, two MGs are connectedto the corresponding nodes of the ADN, and the power interaction iscarried out through the tie line.In this paper, three modes of source-load interaction, ADN-MG interaction and MG-MG interaction are introduced into the dispatchingstrategy presented in this paper, for convenience we call it strategy 1, tocarry out collaborative optimization of target subjects such as generatorunit, energy storage equipment, ADN, MG and load, as shown in Fig. 1.At the same time, the other four dispatching strategies are set to compare with dispatching strategy 1. The five dispatching strategies areillustrated as follows.
