计及需求侧管理的风柴储孤岛微网规划法
|
摘要
将需求侧的可中断负荷和可转移负荷纳入微网规划中统筹考虑,提出一种计及电源和负荷双侧随机性的协同规划方法.在微网规划中将规划成本定义为风电机组、储能及其配套系统的投资运行费用和停电损失;规划效益定义为风力发电效益以及通过需求侧管理减少停电损失.在估算停电损失时综合考虑了电力企业和电力用户的经济损失以及不同类型负荷停电损失的差异性.最后在平衡成本与效益的基础上确定风电机组和储能容量的最优组合,以实现经济性和可靠性的最优平衡,得到安装容量的最优方案.算例分析表明所提出的规划方法能够优化确定风电机组和储能的安装容量,对于风柴储系统的规划与建设有一定的参考价值.
Demand-side interruptible load and transferable load are taken into consideration in the microgrid planning. A collaborative planning method that takes into consideration both the randomness of power supply and load is proposed. In the microgrid planning, the planning cost is defined as the investment operation cost and power outage loss of the wind turbine, energy storage and its supporting system; the planning benefit is defined as the wind power generation efficiency and the reduction of power outage losses through the demand side management. When estimating the loss of power outage, the economic losses of power companies and power users and the differences in power loss losses of different types of loads are taken into consideration. Finally, on the basis of balancing costs and benefits, the optimal combination of wind turbines and energy storage capacity is determined to achieve the optimal balance of economy and reliability; and the optimal solution for installation capacity is obtained. A case study shows that the proposed planning method can optimize the determination of the installed capacity of wind turbines and energy storage; and it has certain reference value for the planning and construction of the storage systems.
