Stochastic programming based coordinated expansion planning of generation,transmission,demand side resources,and energy storage considering the DC transmission system
随着风光电站渗透率不断提高,系统中不确定性的增长对电力系统的扩展规划提出了更高的要求.为抑制风光波动性带来的影响,提出了一种基于随机规划的源网荷储协调扩展规划模型.对系统组成进行广泛建模,包括需求响应服务设施、换流站、直流输电系统、梯级水电站和其他传统组件.此外,考虑了储能系统,以提高新能源消纳水平并降低出力间歇性的影响.负荷侧的需求响应服务用于在用电高峰时段削减并转移负荷.使用随机规划模拟了风电、光伏和负荷的出力不确定性.最后,通过算例仿真验证了所提模型的有效性.
With the increasing penetration of wind and solar energies,the accompanying uncertainty that propagates in the system places higher requirements on the expansion planning of power systems.A source-grid-load-storage coordinated expansion planning model based on stochastic programming was proposed to suppress the impact of wind and solar energy fluctuations.Multiple types of system components,including demand response service entities,converter stations,DC transmission systems,cascade hydropower stations,and other traditional components,have been extensively modeled.Moreover,energy storage systems are considered to improve the accommodation level of renewable energy and alleviate the influence of intermittence.Demand-response service entities from the load side are used to reduce and move the demand during peak load periods.The uncertainties in wind,solar energy,and loads were simulated using stochastic programming.Finally,the effectiveness of the proposed model is verified through numerical simulations.
