Abstract: Aiming at the optimizing operation problem of micro-grid economic, this paper established the optimized dispatching model of centralized control micro-grid, proposed its economic optimizing operation strategy and adopted the self-adaptive firework algorithm to carry out simulation solution for examples’ grid-connected operation of winter in MATLAB software. The optimization results show that the selfadaptive firework algorithm is suitable to solve the micro-grid optimizing operation problem with the characteristics of multiple constraints, multiple target and nonlinearity. From the aspects of algorithm performance and computation cost, this paper compared the self-adaptive firework algorithm, the enchanced firework algorithm and the particle swarm optimization, which verifies that the self-adaptive firework algorithm has better ability of searching optimization.
Key words: micro-grid; optimizing operation; fireworks algorithm; micro power
