可中断负荷(IL)工程的实施将改变电力总负荷，从而影响电网规划。为此，本文分析了规划中考虑IL的必要性，建立了IL项目补偿成本模型，提出了考虑IL的变电站容量规划方法。针对混合整数非线性规划问题的复杂性，采用粒子群算法(PSO)进行求解，并在110KV主电压等级的地区电网中验证了该方法的有效性。计算结果表明，该方法可以在满足区域电力平衡的前提下，降低高峰负荷，减少变电站容量分配，节约建设成本，提高电网规划的经济效益。
The implementation of the Interruptible Load(IL) project will change the total power load and thus influence the network planning. Therefore, this paper analyzes the necessity of considering IL in planning, the compensation cost model of the IL project is established, and the substation capacity planning method considering the IL is proposed. Aiming at the complexity of the mixed integer nonlinear programming problem, the particle swarm optimization(PSO) algorithm is used to solve the problem, and the effectiveness of the proposed method is verified in a regional power grid with a main voltage level of $110kV$. The calculation results show that the proposed method can reduce the peak load and reduce the substation capacity allocation under the condition of meeting the regional power balance, which saves the construction cost and improves the economic efficiency of the power grid planning.
