Comparison of China＇s Wind Power Integration Standard with Similar Foreign Standards

Appropriate wind power integration standards are of great importance to standardize wind power integration and guarantee the safety and stability of the power system. This article describes the wind power integration standards of China explicitly and explains several important points of the newly revised wind power integration standards of China in comparison with standards of Germany, Denmark, etc. The newly revised standards can meet the technical demand of China＇s large-scale centralized development of wind power, and guarantee the safety, stability and economy of the grid and wind farm.

发电厂竞价对调峰辅助服务市场的影响分析

华东电网电源负荷严重过剩,部分省(市)电网出现了低谷调峰容量不足的问题,调峰市场有效地实现了省间调峰互济,但参与调峰市场的发电机组不同的竞价策略会对市场产生不同的影响。文章在华东电力调峰辅助服务市场的背景之下,首先介绍了调峰辅助服务市场的出清流程和买卖双方的电量结算,分析发电机组在制定竞价策略时考虑的4类因素,并根据申报电力、电价的高低制定了4种竞价策略,进一步分析不同的竞价策略对调峰市场以及其他发电机组的影响。通过算例分析,得到了发电机组4种不同的竞价策略对调峰辅助服务市场与其他发电机组的影响,对华东电网即将开展电力调峰辅助服务市场试运行和研究类似问题的电网企业具有重要的参考价值。
