摘要：

为了考核区内省(市)的联络线关口执行结果,我国已有多个区域电网引入控制性能标准(control performance standard,CPS),对改善省间联络线功率偏差和电网频率偏差起到了重要作用.然而近年在用电高峰月份,受端地区省(市)调频资源往往集体紧缺,省间电力现货市场价格高企.按较低固定价格计算CPS罚款的CPS考核机制已无法发挥短时功率平衡和频率兜底作用.为此,提出了网-省主从博弈模型,以求解使省调预留足够自动发电控制可调节容量的CPS考核价格:网调设定CPS考核价格,省调根据考核价格决策日前调度计划,网调再根据省调的调度优化结果调整考核价格,直至该省可调容量或频率偏差满足一定要求.算例结果表明,当考核价格取各类市场价格最高值的8倍时,考核机制可以激励省调在发电能力不足时购买省间现货电量和需求响应量,以满足最大预测负荷及可能的预测误差,从而将互联电网频率偏差控制在一定范围内.

Abstract:

Multiple regional power grids in China have adopted the control performance standard (CPS) to assess the performance of inter-provincial tie-line operations, which has played a significant role in the reduction of both power deviation on inter-provincial tie lines and frequency deviation across the grid. However, in recent years, during peak electricity consumption months, the provinces in recipient regions often face a collective shortage of frequency regulation resources, while inter-provincial electricity spot market prices remain high. The current CPS assessment mechanism, which calculates CPS penalties based on a lower fixed price, has become ineffective as a safe guard for short-term power and frequency balance. Therefore, a master-slave game model between the regional dispatch center and provincial dispatch centers is proposed to determine the CPS assessment price that ensures sufficient reservation of automatic generation control (AGC) adjustable capacity. In this model, the regional dispatch center sets the CPS assessment price, and the provincial dispatch center responds by formulating day-ahead dispatch plan based on this price. The regional dispatch center adjusts the assessment price based on the dispatch optimization results of the provincial center until the adjustable capacity or frequency deviation of the province meets certain requirements. Case study results show that when the assessment price is set at eight times the highest value of various market prices, the assessment mechanism effectively incentivizes provincial dispatch centers to purchase inter-provincial spot electricity and demand response resources in face of generation shortage. This approach enables the system to meet the maximum predicted load and potential forecast errors, thereby maintaining the frequency deviation of the interconnected power grid within acceptable limits.
