电力系统无功优化与电压控制

本文提出了利用调节控制变量使电力系统平衡节点有功功率变量为最小的无功优化与电压控制新方法,建立了相应的数学模型,导出了状态变量与控制变量之间的新的灵敏度关系矩阵,对状态变量的不等式约束利用了迭代约束检索技术进行处理,采用了带上、下界变量的线性规划求解。对6节点算例和24节点实际网络的计算证明该算法具有收敛性好、占用内存少、计算速度快的优点。

REACTIVE POWER OPTIMIZATION AND VOLTAGE CONTROL FOR POWER SYSTEMS

A new method for reactive power optimization that the control variables in power ststems is adjusted to minimize active power increment of the slack bus is presented in this paper. A new sensitivity matrix involving state variables and control variables is derived. In the project, the Iterative Constraint Search(ICS) techniques are utilized for the conversion of nonequal constraints. In the proposed method, the linear model is solved by adopting linear program with upperlower bound variables. The simulation results show that this algorithm is possessed of many advantages: better convergence, less computation time and computation requirements.
