| 摘要: |
| 为了兼顾电网安全稳定和故障下切负荷对社会造成的影响，针对切负荷控制策略如何减少控制代价、并反映各负荷用户间公平竞争等问题，提出了保障大功率缺额场景下系统频率稳定性的切负荷控制优化决策方法。首先从负荷优先级、负荷损失代价、切负荷量精确度三个方面分析了影响切负荷控制效果的要素。在此基础上，利用博弈论原理，构建了各负荷用户作为参与者的多负荷用户非合作博弈模型。然后设计了基于NSGA-II算法的求解方法，通过求解多目标优化模型，获得Pareto整体最优解作为切负荷优化策略。最后通过区域电网典型算例，验证了所提出模型及其求解方法的有效性。 |

| Abstract: |
| There is a need to balance the safety and stability of the power grid and the impact of load shedding in a fault condition. To achieve reduction of the control cost and reflect fair competition among load users, this paper proposes a load-shedding control optimization decision-making method to guarantee system frequency stability under high-power shortage scenarios. First, the factors affecting the effect of load shedding control are analyzed from three aspects: load priority, load loss cost and load shedding accuracy. On this basis, a non-cooperative game model of multi-load users with various load users as participants is constructed using the principle of game theory. Then the NSGA-II algorithm is used to solve the problem. By solving the multi-objective optimization model, the Pareto global optimal solution is obtained as the load-shedding optimization strategy. Finally, the effectiveness of the proposed model and its solution method is verified by a typical example of a regional power grid.
