The calculation of maximum power supply capacity is an important issue in optimal operation of UHV complex large power grid. With the large-scale access of high-proportion renewable energy to the power grid, the problem of power and energy balance is becoming more and more prominent. Considering the stability spinning constraint, coupling section constraint and unit regulation capacity constraint, the calculation problem of maximum power supply capacity presents high-dimensional characteristics, which is difficult to model and solve. According to the limitation of transmission section and the characteristics of partition operation of UHV complex large power grid, an optimal dispatching model of maximum power supply capacity of UHV complex large power grid considering section coupling control was established. Then, the Simplex method (SM), Interior Point method (IP), Simulated Annealing (SA), Beluga Whale Optimization (BWO) and Artificial bee colony algorithm (ABC) were applied to solve the model respectively, and the maximum power supply capacity of the large power grid in the next 15 minutes was calculated. The coordinated optimization scheme of various types of power supply and reserve was proposed. Finally, a regional power grid was taken as an example to verify the model and the solution method. The simulation results show that because of the large scale of the power system and the complex coupling relationship between the sections, the heuristic intelligent optimization algorithm has a long running time, slow convergence speed and low search accuracy. The interior point method converges rapidly, has strong robustness, is insensitive to the selection of initial values, has better stability and computational efficiency, which can provide effective and practical support for power supply and power balance of complex UHV power.

最大供电能力计算是特高压复杂大电网优化运行的重要问题,随着高比例可再生能源大量接入电网,电力电量平衡问题愈发突出。计及考虑稳定旋备约束、耦合断面约束、机组调节能力约束后,最大供电能力计算问题呈现高维特征,难以对其建模及求解。对此,首先根据传输断面限制和特高压复杂大电网分区运行的特点,搭建了考虑断面耦合控制的特高压复杂大电网最大供电能力优化调度模型,然后分别应用单纯形法(SM)、内点法(IP)、模拟退化算法(SA)、白鲸优化算法(BWO)和蜂群算法(ABC)求解模型,计算大电网在日内未来15 min最大供电能力,并提出各类型电源和备用的协调优化方案。最后以某省网为例进行模型及求解方法验证。仿真结果显示,因为电力系统规模庞大和断面间耦合关系复杂,启发式智能优化算法存在运行时间较长、收敛速度较慢、搜索精度不高的问题,而内点法收敛迅速、鲁棒性强、对初值的选择不敏感,具有更好的稳定性和计算效率,可为复杂特高压电网电力保供和电力平衡提供有效实用支撑。

最大供电能力计算是特高压复杂大电网优化运行的重要问题,随着高比例可再生能源大量接入电网,电力电量平衡问题愈发突出。计及考虑稳定旋备约束、耦合断面约束、机组调节能力约束后,最大供电能力计算问题呈现高维特征,难以对其建模及求解。对此,首先根据传输断面限制和特高压复杂大电网分区运行的特点,搭建了考虑断面耦合控制的特高压复杂大电网最大供电能力优化调度模型,然后分别应用单纯形法(SM)、内点法(IP)、模拟退化算法(SA)、白鲸优化算法(BWO)和蜂群算法(ABC)求解模型,计算大电网在日内未来15 min最大供电能力,并提出各类型电源和备用的协调优化方案。最后以某省网为例进行模型及求解方法验证。仿真结果显示,因为电力系统规模庞大和断面间耦合关系复杂,启发式智能优化算法存在运行时间较长、收敛速度较慢、搜索精度不高的问题,而内点法收敛迅速、鲁棒性强、对初值的选择不敏感,具有更好的稳定性和计算效率,可为复杂特高压电网电力保供和电力平衡提供有效实用支撑。

The calculation of maximum power supply capacity is an important issue in optimal operation of UHV complex large power grid. With the large-scale access of high-proportion renewable energy to the power grid, the problem of power and energy balance is becoming more and more prominent. Considering the stability spinning constraint, coupling section constraint and unit regulation capacity constraint, the calculation problem of maximum power supply capacity presents high-dimensional characteristics, which is difficult to model and solve. According to the limitation of transmission section and the characteristics of partition operation of UHV complex large power grid, an optimal dispatching model of maximum power supply capacity of UHV complex large power grid considering section coupling control was established. Then, the Simplex method (SM), Interior Point method (IP), Simulated Annealing (SA), Beluga Whale Optimization (BWO) and Artificial bee colony algorithm (ABC) were applied to solve the model respectively, and the maximum power supply capacity of the large power grid in the next 15 minutes was calculated. The coordinated optimization scheme of various types of power supply and reserve was proposed. Finally, a regional power grid was taken as an example to verify the model and the solution method. The simulation results show that because of the large scale of the power system and the complex coupling relationship between the sections, the heuristic intelligent optimization algorithm has a long running time, slow convergence speed and low search accuracy. The interior point method converges rapidly, has strong robustness, is insensitive to the selection of initial values, has better stability and computational efficiency, which can provide effective and practical support for power supply and power balance of complex UHV power.
