Abstract

The storage battery

which is an energy storage device

plays an important role in ensuring the reliable and economic operation of micro-grid system. In order to study its effect on the economic benefits of micro-grid

allocation model of battery capacity based on optimal economy of micro-grid is established.For CHP micro-grid system within an enterprise

economic optimization dispatch model of micro-grid in grid-connected and islanded modes

in which the minimum operation cost of micro-grid is taken as objective function

is built. A quantitative analysis method for allocating the minimum battery capacity in islanded modes is presented

the battery capacity for achieving the minimum comprehensive cost of micro-grid is determined by solving the proposed model. In the context of spot power prices

the improved genetic algorithm is chosen to optimize the output of battery and the electricity purchases with sales between external network and micro-grid in different times

the optimal charging-discharging strategies of battery are drafted. The numerical tests show that the built model

dispatch strategy is effective and the algorithm is applicable.
