doi:10.11930/j.issn.1004-9649.202109126

Abstract

Abstract: The wind turbine, photovoltaic, and cooling, heating and power load forecasts have strong random uncertainties, which increase the difficulty of dispatching and operating island microgrids. This paper studies the environmentally and economic dispatch problem of the islanded microgrid with combined cooling, heating and power. The interruptible load is incorporated into the islanded microgrid as a virtual power generation resource to participate in the system operation, while considering the economy and environmental of scheduling. Fuzzy chance constrained programming is used to deal with the uncertainties, and then the model is transformed into deterministic equivalence. A multi-objective processing method based on satisfaction indicators is used to take into account the economic goals and environmental goals. Numerical example verifies the effectiveness of the proposed model.

Key words: CCHP, islanded microgrid, chance constrained programing, environmental and economic dispatch
