Coordinative Dispatching Between Active Distribution Network and Main Network

doi:10.3969/j.issn.1000-7229.2016.01.006

Abstract

Abstract:

Active distribution network (ADN) with more autonomy in dispatching is able to control distributed generators, energy storage equipments and active load, which can realize the efficient operation of distribution network. The dispatching schedule of main network and distribution network influences each other. Besides the operating cost, the coordination of main network and distribution network should be considered when we make the optimal schedule of ADN. This paper provides a real-time information interaction mode, carries out modeling analysis on active load and energy storage equipments, and proposes a coordinative dispatching model based on real-time pricing. In addition, a parallel optimization algorithm is presented aiming at the scheduling model. Simulation results on the IEEE 9 node system connected with a distribution network verify the validity of the model and the algorithm. Finally, we analyze the influences of demand response, energy storage equipments and power limit in interconnecting lines on the dispatching schedule.

Key words: active distribution network (ADN), coordinative dispatching, demand response, energy storage equipment, distributed generator
