【摘要】 构建一个完善的电力市场已成为全世界的一大趋势。由于系统频率是否发生偏移可以反映市场的供需是否处于平衡状态,所以可以利用辅助服务方式之一的负荷跟踪服务通过负荷监测器实时监测负荷波动,并将负荷信息传送到发电端,进行功率调整。本文在此基础上对负荷跟踪控制模型进行市场下的改进,考虑市场因素,形成控制结构,根据可能出现的各种发电及负荷变化对模型加以修正,对其动态响应进行实时模拟,得到优化模型。利用该模型可以实现供求平衡,调整系统频率,提高供电质量。更多还原

【Abstract】 Setting up a developed electricity market is the tendency throughout the world. The paper discusses the relations of the imbalance between the supply and the demand to the frequency deviation of the system. The load following, one of the auxiliary services, lets generator get a demand signal directly from the load monitors. On the basis, the paper proposes a load following controller,considering the market environment,just to deal with the frequency deviation by contrasting the results of the dynamic response, which are obtained by modifying the old one.更多还原
