摘要
本文基于全寿命周期理论,提出了微电网项目全寿命周期框架下的优化配置模型。综合考虑微电网初始投资、运行维护及故障、折旧成本,以及供能、节能环保收益,建立了微电网全寿命周期内的净现值收入计算模型。以全寿命周期内的净现值收入为目标函数,计及分布式电源出力、储能充放电、运行电压和频率、供电可靠性、与主网交换功率等约束条件,建立优化配置模型,并采用粒子群算法进行求解。结果表明:与传统的优化配置方法相比,该方法得到的优化配置方案,能够实现微电网在全寿命周期内的净收益最优,确保投资的最佳经济性,为微电网工程规划和建设提供指导,促进其市场化、产业化发展。
Based on the whole life cycle theory,the optimal configuration model of the microgrid project under the life cycle framework is proposed.A calculation model of NPV income in the whole life cycle of microgrid is established,with the initial investment,operational maintenance and failure,depreciation cost,energy supply,energy saving and environmental benefits of the microgrid taken into account.The net present value income in the whole life cycle is taken as the objective function,and the optimal configuration model is built up with the constraints of distributed power supply,energy storage and discharge,operating voltage and frequency,power supply reliability,and the switching power of the main network.The particle swarm optimization algorithm is used to solve the problem,the results show that compared with the traditional optimal allocation method,the optimized configuration scheme obtained by this method can achieve the best net income in the life cycle of the microgrid and ensure the best econ-omy of investment.It will provide guidance for the construction of microgrid project,and promote the marketization and industrialization of the microgrid.
