MLR-MPSO-based Arrangement Optimization of Monitoring Points in Transmission Networks
The safe and stable operation of transmission networks is very important.Once a voltage sag occurs,it may se-riously impact the operation of power system.Therefore a series of monitoring devices are mandatory in a transmission network in order to obtain the operation status.However the deployment of these monitors should consider efficiency since number-excessive planning results in not only high investment and maintenance costs,but also unnecessary redundant in-formation.The present work made a preliminary attempt to propose and analyze the utility of a MLR-MPSO-based strate-gy of determining the optimal number and locations of monitoring points in a transmission network.First,in order to re-duce the redundancy of monitors,Mallow's Cp was introduced as the evaluation criterion for the linear regression model,and the particle swarm optimization algorithm was modified.Then taking minimization of the sum of squared errors in the unmonitored bus voltage as the objective,the candidate arrangement strategies for the entire system were further selected.The correctness and the effectiveness of the proposed strategy was verified by a MATLAB/Simulink simulation using the IEEE 30-BUS system.
