摘要:近年来，包含可再生能源发电的微电网技术得到了快速发展。针对包含多种新能源和新型负荷的微电网存在能量利用效率低的问题，研究了混合能源微电网的优化调度问题，并在优化调度模型中考虑需求侧响应和低碳效益。优化过程中，将含有光伏、风机、热电联供系统、电动汽车的微电网为研究对象，建立各电源出力模型。以包含燃料费用、运行维护费用、购售电费用、微电源折旧费用及碳处理费用的总费用最小为目标函数，在满足各类约束条件下，采用改进的萤火虫算法求解目标函数。结合算例，计算不同运行方案下微电网总运行费用，并分析各方案的低碳效益，寻求经济性和低碳效益的平衡以得到该微电网最佳运行方案。
Abstract：In recent years, micro grid technology including renewable energy generation has been developed rapidly. According to the problem that the energy efficiency of micro grids containing multiple new energy sources and new loads is low, this paper focuses on the optimal scheduling of hybrid energy micro grid, and considers the demand response and low-carbon benefits in the optimal scheduling model. In the optimization process, we take the microgrid which contains photovoltaic (PV), wind power, combined heat and power (CHP) and electric vehicles (EV) as the object of study, and construct the output models for each resource. The objective function aims to minimize the total cost including gas cost, operation and maintenance cost, electric power purchase from the main grid, depreciation charge for micro power and cost of carbon dioxide emission. Under the constraint conditions, we adopt the improved firefly algorithm (FA) to solve the objective function. With case study, we calculate the total operation cost of micro grid under different scenarios, analyze the low carbon benefits of each scheme, and seek the balance between economy and low carbon to obtain the optimal operation scheme of micro grid.
