| 摘 要： | 针对当前综合能源系统规划未考虑联络线峰谷差对电网运行的影响，提出了考虑联络线峰谷差和电网运行效益的综合能源系统规划方法。以电网全年运行费用和综合能源系统年费用标幺值之和最小为目标，以联络线传输功率为约束，建立了综合能源系统优化规划模型；利用精英保留策略遗传算法和分支定界法求解综合能源系统设备配置及优化调度，采用最优潮流求解计及联络线实际传输功率的电网运行效益。对改进的IEEE 30节点系统进行仿真分析，验证了所提模型的有效性；同时，控制联络线峰谷差率可以降低电网安全运行风险，减少综合能源系统接入带来的电网运行成本。

| Abstract: | Aiming at the current situation that the IES(Integrated Energy System) planning does not consider the impact of the peak-to-valley difference of the tie line on the operation of the power grid, an IES planning method considering both the peak-to-valley difference of the tie line and the power grid operation benefit is proposed. The optimal planning model of IES is established, which takes the minimum per unit sum of the annual operating cost of the power grid and the annual cost of IES as the objective function and with the tie line transmission power as the constraint. The elite energy reserve genetic algorithm and branch and bound method are used to solve the equipment configuration and optimal scheduling results of IES, and the optimal power flow is used to calculate the power grid operation cost under the given transmission power of the tie line. The simulative results of the improved IEEE 30-bus system verify the effectiveness of the proposed model. Meanwhile, controlling the peak-to-valley difference of the tie line can reduce the safety risk and the operation cost of the power grid brought by the access of IES. |
