Research of Microgrid Optimization Scheduling Strategy Based on Customer Interaction

摘要

With the widespread application of distributed generation and increasingly requirements of power supply quality and reliability, a new type of of power system structure named "Microgrid" was proposed in order to seek a way to ensure environmental sustainability and to meet user demand for energy supply. In the process of development of the smart grid, the distribution network in the form of the transition from a passive to an active network Meanwhile, the microgrid is an important network model of future intelligent power distribution system, the operation control system is key to ensuring microgrid safe, economical and reliable operation. This paper describes the microgrid control system, microgrid optimal scheduling modules, and demand-side response measures. The purpose of microgrid optimizing operation is the coordination and optimization among microgrid, distribution network and users. Three demand response strategies related to time shift, peak shift and load shedding are introduced to the microgrid hourly optimization scheduling.
