Economic Dispatch of Wind Farm Cluster Integrated Power System Considering High Energy Load

Abstract

It is difficult to realize the economic dispatch for the large-scale wind power integration system. This paper thus presents a more comprehensive economic dispatch scheme, which considers the high energy load as a schedulable resource. The coordinated dispatch is achieved with the high energy load and wind farm cluster through the coordination layer. The multiple target mathematical models of the economic dispatch are established for the wind integrated power system. In this method, the income of the colony coordination layer maximization and the cost of control center minimization are assumed as the objective functions on the condition of output restriction, with power system security and output power of wind farm. The multi-objective cuckoo algorithm is used to perform the optimal solution. Finally, the mathematical models and the optimization algorithm are simulated respectively. The results verify the correctness of the proposed dispatch scheme and the effectiveness of the algorithm.
