Coordinated optimal dispatching of distributed generation based on quantum differential evolution algorithm

In allusion to economic operation of distributed generation (DG) system considering demand response, a comprehensive optimal mathematical model, in which the fuel cost and the cost of operation and management, the interaction cost, the compensation cost for the outage of interruptible loads and electricity cost of demand side are taken into account, is established. Meanwhile, to implement effective interaction of energy a demand side response model is added to the established optimal model. A kind of quantum differential evolution (QDE) algorithm is proposed to solve the established optimal model. Based on the idea of differential evolution and using parallel and collapse properties of the quantum calculation theory and considering probabilistic nature of quantum bit in the selection strategy, the proposed algorithm possesses strong robustness and global searching ability. Calculation results of a microgrid containing different kinds of DGs show that the established coordinated optimal dispatching model and the proposed algorithm are reasonable and effective.
