Abstract:As a large number of flexible elements such as distributed power and flexible load are connected to microgrids, the economic improvement of microgrids has become an important topic through rational energy distribution. In this paper, an economic scheduling model considering the load demand for a microgrid system under the mechanism of a peak–valley tariff is proposed.

3. Case StudyWangjiazhai project contains multiple elements of the source–network-load storage system in the Baiyangdian region, is a typical scenario for the application of new energy, and has strong representativeness [32]. This paper takes the Wangjiazhai project as the practical application background. To better reflect the dynamic dispatching occurring in the microgrid, four scenarios are discussed and investigated fully.

1. IntroductionIn recent years, renewable energy sources have been vigorously developed to solve the energy shortage and environmental pollution problems. The penetration rate of photovoltaic and wind power sources have been increasing in the distribution network. The traditional distribution network is gradually transforming into the active distribution network [1].
