Coordinated Control Strategy for Multi Micro Energy Systems Within Distribution Grid Considering Dynamic Characteristics and Contradictory Interests

As a typical form of integrated energy system, micro energy system (MES) is promoted and popularized at the terminal of distribution grid. To achieve the efficient and reliable energy utilization of MES, two main problems need to be solved: how to consider the dynamic characteristics of heterogeneous energy resources and diverse MES operating states under multiple time scales and how to coordinate the interests of both MES operator and distribution grid operator. This paper aims to establish the models of specific energy devices in MES and propose a coordinated control strategy for multi MESs within distribution grid considering dynamic characteristics and contradictory interests. The proposed strategy is presented from the MES side and distribution grid side with consideration of different control objectives under day-ahead dispatch, intra-day dispatch and emergency control circumstances. A case study based on IEEE 33-bus system with MESs connected is conducted to verify the effectiveness of the proposed strategy.
