“…For a traditional distribution system, the restoration problem can be considered as a multi-objective problem. Many methods have been proposed to solve this NP-complete problem, such as expert system [1,2], heuristic research [3,4], genetic algorithm [5] and multi-agent methods [6]. Because the impacts of DGs were not considered in these researches, these strategies are unsuitable for the restoration of distribution systems with DGs.…”

Considering the probabilistic of the wind power and the solar power, a fault recovery method for distribution systems with the wind power and the solar power is presented in this paper. For the wind power, a simplified steady-state equivalent model of an asynchronous wind generator is added into the Jacobian matrix to consider the impact of the wind power on systems. For the solar power, its output is considered as an injected power which is related with solar irradiance. Three-point estimate is employed to solve the probabilistic power flow of distribution systems with the wind power and the solar power. The restoration is described as a multi-objective problem with the mean of the system loss and the number of switch operations. Fast elitist non-dominated sorting partheno-genetic algorithm is used to solve this multi-objective problem. IEEE 33-bus system is used as an example and the results show that the models and algorithms in this paper are efficient.
