With the deregulation of power market and integration of large-scale intermittent renewable generation, the operation of modern power system is faced with more and more uncertain factors. Traditional deterministic methods are hard to meet the requirements for the analysis and control of power system under uncertainty. Therefore, it's necessary to introduce risk assessment methods into the daily operation...
The massive integration of wind power brings more challenges to the safe operation of power system. In this paper, risk assessment methods of power system with wind power integration are studied by using DSR (dynamic security region) and risk assessment theory. The basic construction method of DSR boundary is introduced. The risk index calculation and comprehensive analysis method of wind power integration...
With deregulation of power system market, the uncertainties in modern power system increase, risk assessment has become an effective tool for power system analysis considering the uncertainties. A software named as BTNRAS (Bulk Transmission Network Risk Assessment System) is presented in this paper. Besides quantitative risk evaluation indices, BTNRAS provides some auxiliary functions, such as risk...
In the traditional power transmission network planning, deterministic analysis methods are widely used. In such methods, all contingencies are deemed to have the same occurrence probability, which is not reasonable. In this paper, risk assessment is introduced to the process of transmission network planning considering the probabilistic characteristics of contingencies. Risk indices are given to determine...
