    Abstract: In order to enhance computing accuracy and universality of photovoltaic (PV) power forecasting, this paper proposed a online-learning method based on leaky-integrator echo state network(LIESN). Leaky-integrator neurons were introduced to plain ESN and the short-term memory ability was promoted. The impact of parameters of LIESN on PV power forecasting performance was analyzed and an optimized model was obtained. The model was trained by least squares online learning algorithm and final forecasting was obtained. By practical examples, complicated model can be established and applied to various weather conditions. The forecasting accuracy was superior to the BP neural network and plain ESN and the validity of proposed method is testified.
    Key words: echo state network; leaky-integarator; neurons; photovoltaic power forecasting; online learning
