摘要

In this paper, we present optimal power planning model using Monte Carlo simulation approach we developed to analyze the behavior of power system and the effect of introducing batteries into power system with consideration of wind power uncertainty and plural operational states under the situation of large-scale wind power installation. Unlike conventional approaches, our approach can easily describe the stochastic nature of wind power fluctuation by ARMA model and the behavior of thermal power plants which can be affected by wind power uncertainty. As a result, the model presented reveled the parallel operation of GCC caused by wind power uncertainty which cannot be seen in the conventional model. Moreover, numerical results of our study clearly show that batteries can decrease both generation costs and CO_2 emissions by mitigating the effect of wind power uncertainty. While we assume the battery which is utilized for load levelling and mitigating wind power uncertainty, another use of battery such as load frequency control should be considered and optimized in the future work.
