Study on Risk Assessment Applied in Power Grid Planning

Abstract

While summarizing current reliability standards at home and abroad, application of reliability assessment method into power grid planning based on risk theories is studied. Probabilistic analysis and reliability assessment are combined to investigate the ability of a power system withstanding serious contingencies. The state enumeration method is used and risk indices, indicating the adequacy and security of a power system, are quantitated. A new frame of grid planning for power systems considering risk indices is then constructed. The application in the IEEE RTS-79 test system shows that the risk assessment method is valuable and beneficial to development and consummation of traditional power grid planning methods.

Study on coupling and coordinated development of green development of power grid and ecosystem—from the perspective of energy industry chains

“…In terms of the energy industry chain, the interconnection between power grid advancement and the ecological environment manifests primarily in three dimensions [4][5][6][7][8][9][10]. Concerning the creation of a green power grid development evaluation index system, assessment criteria can be devised based on three key dimensions: collaboration with upstream green initiatives, achieving internal sustainability goals, and fostering downstream environmental progress [11][12][13].…”
