Power Dispatch Strategy for Wind Farm Based on Virtual Market

In this paper, we propose a decentralized control strategy to dispatch and control the output power for wind farm. In this strategy, the power control system is supposed to operate as a virtual market place. Every wind generator is treated as a buyer agent or a seller agent. The buyer and seller agents cooperate and compete to process transactions for setting value of power. The market place manager acts as a facilitator by giving necessary information to agents and managing communication between agents, and also as a mediator by proposing solutions to agents or stopping them to get into infinite loops bargaining back and forth. The aim of this work is reduce output power variation and balance the generator fatigue index by using the decentralized control scheme. Simulations demonstrate the effectiveness of the scheme.
