Stand-alone micro-grid distributed generator optimization with different battery technologies

For the reason that wind, solar power and other renewable energy sources are stochastic volatility, in order to improve the reliability and economical efficiency of system power supply for the micro-grid distributed power reasonable configuration is an important issue for micro-grid planning and construction. This paper aiming at a minimum optimization goal of overall costs, including equipment investment costs, replacement costs, operation and maintenance costs, fuel costs and environmental conversion costs, and for the condition in the system power supply constraints, established a hybrid micro-grid distribution power optimal allocation model for mixed micro-grid of islanding operation considering different battery technologies. Take an independent micro-grid of a certain mountain school for instance to optimize the design, applying HOMER software simulation and optimization of the system to verify the reasonableness of the configuration model. In addition, analysed the effect on the optimized result with diverse battery technology.
