Combination and Application of Virtual Power Plant, Microgrid and Demand Response Technology in Multi-court Distribution Network for Energy Use Optimization

The energy use optimization can effectively improve the comprehensive operational benefit of the distribution court. Nowadays, the energy use optimization in distribution court is facing serious challenges under the background of large scale DG coupling. The global optimization of the energy use in distribution network with multiple distribution courts is more difficult. In order to solve this problem, a comprehensive solution is proposed in this paper. The goals for energy use optimization in the distribution court are firstly discussed. The virtual power plant technology, microgrid technology and demand response technology are introduced and compared. By combining and applying the three key supporting technologies, an idea is proposed for the energy use optimization in the multi-court distribution network. The structural composition, functional framework and optimal control of the multi-court distribution network for the idea implementation are illustrated. Finally, a conclusion and an outlook is given.
