考虑需求侧管理的微电网调度模型与策略

微网系统中可控机组的调节能力有限,随着负荷峰谷差的增大以及分布式新能源的接入,给微网调度带来新的挑战。因此,提出通过考虑需求侧管理对可控负荷进行有效控制,以起到削峰填谷的作用,避免了可控机组的频繁调节,从而提高机组的运行效率;此外,通过可控负荷随间歇性能源的出力,提高了微网系统消纳间歇性能源的能力。对某微电网进行分析表明,所提出的控制策略有效可行。

Model and Strategy of Microgrid Dispatch Considering Demand Side Management

The regulation ability of the controlled unit in microgrid system is limited. As the increase of load peak valley difference and the access of distributed new energy, it brings new challenge for microgrid dispatch. By considering the demand side management, the controllable load can be peak load shifting and the frequent adjustment of the controlled units are avoided which improves the efficiency of units. In addition, using the controllable load to follow the output power of intermittent energy, it improves the capacity of the intermittent energy consumption in microgrid system. Finally, by the calculation of a microgrid system, the feasibility of the proposed method is verified.
