冷热电联供型孤岛微电网环保经济调度模型

分布式风光伏及冷热电负荷具有较强的不确定性，增加了孤岛微电网的调度运行难度。研究冷热电联供型孤岛微电网的环保经济调度问题，通过在孤岛微电网中融入可中断负荷，将可中断负荷视为虚拟发电资源参与微电网调度运行，同时考虑微电网运行方案的经济性和环保性。采用基于可信性测度的模糊机会约束规划处理分布式风光及冷热电负荷的不确定性，进而转化为确定性等价类。采用基于满意度指标的多目标处理方法兼顾经济目标和环保目标。算例分析验证了模型的有效性。

Environmental and Economic Dispatch Model for Island Microgrid of Combined Cooling,Heating and Power

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.
