【 摘 要 】

This paper builds a power supply system including wind power, PV, storage and demand-side response. Taking the largest amount of clean energy consumption as the primary goal, considering the costs of power supply, adding power balance, grid reliability, upper and lower limits of the energy storage system, demand-side response, and wind power and PV output limits, the study intends to distinguish the different power price development models. It establishes four scenarios including energy storage system and demand-side responses not considered, only energy storage, only demand-side responses, energy storage system and demand-side response are considered simultaneously. Through comparative analysis, the energy storage and the demand-side response can effectively improve the wind power and PV consumption rate about 10% and improve the power supply stability and economy. Establish a penalty mechanism on the demand-side response, shift the load, reduce the power purchase from grid, and save about $2230 by the simulation. This method can enhance the flexibility and reliability, effectively reduce the peak value, reduce the cost of power purchase.
