考虑需求侧响应的配电变压器效益潜力评估

摘要

采用核心平滑密度估计得到电量总体密度曲线,分析了配电变压器的尖峰特性,并进一步建立配电变压器全寿命周期成本模型,分析了需求侧响应下配电变压器尖峰负荷转移与投入资金的关系,从而建立考虑需求侧响应的配电变压器效益潜力评估模型,并进行了算例仿真,仿真结果表明,在需求侧响应下,配电变压器效益具有较大的潜力.%In this paper,the kernel smoothed density is used to obtain the total power consumption density curve,and the peak characteristics of the distribution transformer are analyzed.Furthermore,the distribution transformer life cycle cost model is established,and the relationship between the distribution transformer peak load transfer and investment under the demandside response is explored so as to establish the evaluation model for potential benefits of distribution transformers considering the demand response and thus the corresponding numerical simulation is conducted.The simulation example shows that under the demand-side response,the distribution transformer has great potential.
