동적 계획법을 이용한 계통 연계된 마이크로그리드의최적 운영 계획에 관한 연구

초록

The Korean government has an electricity supply plan using distributed energy resources for 18.4% of the total power production in 2030. We develop an optimization model for cost-effectively operating a grid-connected microgrid, which is a discrete energy system consisting of distributed energy resources and power by the main grid. The power production cost of a microgrid, compared to the nuclear and thermal power plant, has been known to be high. Thus, a governmental support, such as an incentive or electricity price policy, is necessary to promote the use of distributed energy resources. By using our model and dynamic programming, the effects of several policies on optimal operation of microgrids are analyzed.
