This paper proposes a new method for probabilistic reliability evaluation with Tabu Search (TS) of meta-heuristics (MH). Recently, the power networks increase the degree of the uncertainties due to the new environment of power network liberations, the emergence of the renewable energy, etc. The importance of the probabilistic reliability assessment of electric power systems has been recognized as...
Power grids have traditionally been planned and operated to withstand without resulting in cascading events transmission outage contingencies of the N-1 or N-2 kind. However, in actual operation, power grids are potentially vulnerable to cascading outages. Reliable operations therefore require a risk-based approach to monitoring and managing the probability and impact of potential cascading outages...
In the practical power system operation, sometimes, some reasons will lead to local power network splitting, generate islanded power network operating. In order to ensure islanded power network operation safety and stability, it is urgently need to know power flow distribution for islanded power network. However, conventional power flow model can't reflect the important features for islanded power...
We propose a way to find an appropriate balance between economy and reliability in power system operation using A-life (artificial life) simulation. A-lives move in a two dimensional space that represents operating condition of the model system. They move by a principle selected between two strategies, one of which is seeking economy, while the other is seeking reliability. Two strategies are selected...
