摘　　要：随着新型电力系统的发展,新能源和储能电站大量并网。在南方新能源和储能电站多数以110 k V及以下电压等级并网。这给现有的电网AGC控制带来了新的挑战。针对这一情况,该文提出了有功控制就地平衡的原则,并基于该原则提出了一种AGC优化控制方法,将220 kV及以上和110 kV及以下电压等级并网的电源按不同目标控制。对于110 kV及以下电压等级并网的新能源与储能电站,该文提出了采用调控云数据的ACE分配方法,解决了调控云数据传输速度与AGC控制周期的矛盾。所提方法 2021年在南方某省级电网部署应用。所提方法应用期间,应用省份全省网损率显著降低,新能源密集上网地区变压器重载率降低。运行数据验证了所提方法的有效性。With the development of new power systems,a large number of new energy and energy storage power stations are connected to the grid. Most of the new energy and energy storage power stations in the south are connected to the grid at voltage levels of 110 kV and below. This brings new challenges to the existing grid AGC control. In view of this situation,this paper proposes the principle of local balance of active power control. Based on this principle,an optimal control method for AGC is proposed. The grid-connected power supplies with voltage levels of 220 kV and above and 110 kV and below are controlled according to different goals. For the grid-connected new energy and energy storage power stations with voltage levels of 110 kV and below,this paper proposes an ACE allocation method that uses cloud data to regulate. The contradiction between regulating cloud data transmission speed and AGC control period is resolved. The proposed method was deployed and applied in a provincial power grid in southern China in2021. During the application period of the proposed method,the grid loss rate of the applied province and the whole province was significantly reduced,and the overload rate of transformers in the new energy-intensive grid-connected areas was reduced. All the data collected and processed has verified the effectiveness of the proposed method.
