Reliability Analysis Method for Microgrid with Intermittent Distributed Generations
the paper concerns on the reliability analysis method for microgrid with the intermittent distributed generations (DGs) and their power supply failure. Some types of DGs, such as photovoltaic and wind turbine, have the characteristic of intermittent and uncontrollable, which leads to unstable power output. It is worth to analyze and quantify the microgrid influence of DGs on the power supply reliability. In the paper, taking wind turbine as example, a multi-states power output model for intermittent DGs was provided with Markov chain. And then, a microgrid reliability analysis method, considering the influences of DGs intermittent and power supply failure, was proposed. The probability distribution of loads and power supplies are used, and a quantitative reliability indicator was given in the method, which could well reflect the microgrid reliability on various random factors. At last, an actual microgrid in Nanjing City was used to verify the feasibility and effectiveness of the proposed method.
