Time-of-use power price mode-based study on power accommodation model of distributed wind-photovoltaic joint power generation system

The method of time-of-use ( TOU) power price can reflect the market-oriented behavior of power load and guide user's power consumption time-segment，and then promote the accommodation and utilization of the renewable energy sources． Based on the three-stage classification method of power load，a model for the accommodation of the power connected from the distributed wind-photovoltaic joint power generation system to the distribution network system under the time-of-use ( TOU) power price mechanism is proposed herein． For this model，the internal time-of use ( TOU) power price of distribution network is adopted to enhance the grid-connected accommodated power，while the simulated annealing algorithm is combined to optimally solve the model． Finally，through the relevant simulative calculation case，the feasibility of this method for promoting the accommodation of the power from the distributed wind-photovoltaic joint power generation system and obtaining the win-win effect by both the distribution network and the user is verified．
