摘要:

我们考虑在间歇负荷的配电网中,切换电容器和D-STATCOM的联合控制问题。该控制问题被建模为具有机会约束的双时间尺度优化功率流问题,旨在最小化功率损耗同时限制由于负载快速变化导致电压违规的概率。控制问题构成了确定控制设备尺寸的优化问题的基础,通过最小化预期功率损耗成本和资本成本之和来确定设备尺寸。我们开发了计算高效的启发式方法来解决最优配置问题,并实现了实时控制。在具有高性能计算(HPC)负载的电路上的数值实验表明,所提出的配置和控制方案在仅增加适度成本的情况下显著提高了电压调节的可靠性。

英文摘要:

We consider joint control of a switchable capacitor and a D-STATCOM for voltage regulation in a distribution circuit with intermittent load. The control problem is formulated as a two-timescale optimal power flow problem with chance constraints, which minimizes power loss while limiting the probability of voltage violations due to fast changes in load. The control problem forms the basis of an optimization problem which determines the sizes of the control devices by minimizing sum of the expected power loss cost and the capital cost. We develop computationally efficient heuristics to solve the optimal sizing problem and implement real-time control. Numerical experiments on a circuit with high-performance computing (HPC) load show that the proposed sizing and control schemes significantly improve the reliability of voltage regulation on the expense of only a moderate increase in cost.
