Cost compensation mechanism for high wind power integration considering demand respond

The rapid growth of wind energy is presenting great challenges to the traditional dispatch and control of power grid since the wind energy which has an adverse effect on peak regulation is intermittent, fluctuant and uncontrollable. To improve the consumption level of wind energy, this paper proposed a cost compensation mechanism to facilitate the demand side to participate in peak regulation when a large-scale wind power integrates into the grid. Firstly, the complementary relationship of the regenerative electric heating, plug-in electric vehicles and interruptible load in capacity and response characteristics has been analyzed. Based on the analysis, a stochastic unit commitment model with the demand side participant is established, which facilitates the consumption of wind energy. Based on the optimization results, cooperative game theory is introduced to propose the method to work out the allocation results of the demand side response compensation cost, which is based on Shapley value method. Calculation example demonstrates that the cost compensation mechanism facilitating the demand side's participation in the wind power consumption is effective, namely reducing the operation cost of thermal power units while maximizing the flexibility of the demand side and the consumption of the wind energy.
