Optimization Operation of Micro-grid Based on Improved CSO

文中主要考虑包含传统火电机组在内的冷热电三联供型微电网的经济运行。在充分利用新能源的前提下,验证"以热/冷定电"优化策略的正确性。首先建立包含传统火电机组在内的冷热电三联供型微电网的数学模型,综合考虑各出力源的运行维护成本、燃料费用、环境治理费用和购/售电费用后,采用改进鸡群算法进行算例仿真分析,算例结果表明,所述算法可行且"以热/冷定电"优化策略正确。

This article mainly considers the economic operation of the micro-grid combining cold,hot and elec- tricity ,which includes traditional thermal power unit. On the premise of making the best use of new energy sources, the optimization strategy of ＇regulating electricity by hot or cold＇ will be verified. Firstly,the mathematical model of the micro-grid combining cold,hot and electricity, including the traditional thermal power will be built. After considering the operation maintenance cost of every output source ,fuel cost, environment governance cost and the purchase/sale cost of electricity,the improved chicken algorithm will be used to make example simulation analysis,the result of which suggests that the algorithm is feasible and the optimization strategy of ＇stimulating elec- tricity with hot and cold＇ is correct.
