【摘要】：在大电网平台下,利用优质电源对多个电网进行资源优化配置是缓解中国电网调峰压力的一种重要途径。由于单一电站甚至机组通常担负向多个省网送电任务,且受制于差异极大的不同省(市)级电网负荷、受电量等因素,给电站同时响应多电网负荷调节需求造成很大困难。以华东电网为背景,提出3种以调峰为控制目标的电站网间出力分配方法。前两种方法基于对电网余荷的全时段统一评价和峰谷分段评价策略,建立了不同的二次规划模型;方法三引入负荷相对排序策略,以各电网面临时段负荷在其负荷序列中的高低作为启发信息,进行出力分配。通过华东电网直调电站群模拟调度表明,3种方法都能切实解决电力系统网间出力分配问题,给出满意的多电网调峰结果。
[Abstract]:Under the platform of large power grid, it is an important way to reduce the peak-shaving pressure of China's power grid by optimizing the allocation of resources to multiple power grids by using high-quality power sources. Because a single power station or even a unit usually takes on the task of transmitting power to several provincial networks, and is constrained by different provincial (municipal) power grid loads, and so on, it is very difficult for the power station to respond to the demand of multi-grid load regulation at the same time. Under the background of East China Power Grid, three methods of power distribution between power stations with peak-shaving as the control target are proposed. The first two methods establish different quadratic programming models based on the strategy of unified evaluation and peak-valley segment evaluation of the residual load of power network. In method 3, the relative ranking strategy of load is introduced, and the magnitude of load in the load sequence is taken as the heuristic information, and the load distribution is carried out. The simulated dispatching of direct-shunting power stations in East China Power Grid shows that all the three methods can effectively solve the problem of power generation distribution between power systems and give satisfactory peak-shaving results for multi-grid.
