Abstract

With the development of energy interconnection system, diversified resources represented by energy storage, demand response and distributed generation(DG) are deeply involved in power grid operation. As an integrator of multiple distributed resources, distribution system needs to optimize and regulate distributed resources to improve the elasticity of distribution system. Centralized optimization strategy for the traditional distribution network has several limitations in the case of multi-resource fusion. This paper analyzes the characteristics of multiple distributed resources firstly, and then establishes a two-layer distributed optimization model for highly elastic distributed network which regulates several kinds of distributed resources through coordinating global controller and local controllers in order to ensure more DG consumption under the certain voltage quality, and to improve the utilization level of renewable energy. IEEE 14 nodes and IEEE 69 nodes distribution network systems are used for case study. The results of the two optimization strategies are compared. The applicability and advantages of the two-layer distributed scheduling model are verified.

Key words： Multiple distributed resources highly elastic distributed network two-layer distributed optimization model voltage quality
