Abstract: In order to reduce impact of randomness generation capacity on power system, there is a need to study generation power forecast. Via analysis of factors of impact on photovoltaic generation power, this paper established the forecast model in Matlab based on BP neural network theory, realizing the short term forecast of output power and giving the method of improved forecast accuracy based on Markov chain.
        Key words: photovoltaic power generation; prediction model; neural network; Markov chain
