By use of power system analysis software BPA, the power flow of a certain regional power network was simulated; From this the nodes and zones with weak voltage stability were found out , and an optimal configuration scheme of pharos measurement units(PMUs) in this regional power network was proposed. By means of indentifying equivalent impedances with recursive least square method, the voltage stability...
A lot of exogenous factors and the sequential variance held by the power system itself should be considered in the medium and long term load forecasting of power system. In view of these characters, the study on long and medium term load forecasting is worked by the means of multi-level recursive regression in this paper, and the model is established based on it. Forecasting is divided into two parts:...
