提出一种基于单位综合发电成本的多能源微网系统(micro-grid with multi-energy system,MGMES)经济性评价指标,建立计算单位综合发电成本的优化模型。该模型综合考虑安装地点的MGMES一次性投资成本、燃料、环境运行成本,采用基于粒子群算法的配置和运行交错的优化方法,求解特定负载和安装地点优化的单位综合发电成本,最后根据风、光资源的分布,选取5个典型安装地点作为MGMES的安装地点并进行实例分析。
This paper presents an economic evaluation index of multi-energy grid-based multi-energy system (MGMES) based on integrated power generation cost per unit, and establishes an optimization model to calculate the integrated power generation cost per unit. The model considers the MGMES one-time investment cost, fuel and environmental operation cost at the installation site, and adopts optimization method based on Particle Swarm Optimization (PSO) algorithm and operation staggering to solve the unit integrated power generation cost optimized for a specific load and installation location. Finally, Light distribution of resources, select five typical installation sites as the installation site MGMES and case analysis.
