摘要:

在未来的低碳英国(GB)电力系统中,对增强频率响应(EFR)的需求预计将显著增加。提供EFR的单向式方法之一是将电力电子补偿器(PEC)用于负载点电压控制(PVC)以利用负载的电压依赖性。本文通过量化城市家庭用电部门采用PVC可获得的总EFR、装置的投资成本以及使用PVC的经济和环境效益,研究了这种技术在未来GB电力系统中的技术经济可行性。量化是基于随机国内需求模型和通用的中,低压配电网的GB和随机机组组合(SUC)模型的城市地区的安全故障后频率演变的约束条件用于价值评估。在2030年的背景下,在电池储能系统(BESS)的不同渗透水平下,对电动汽车和热泵进行“智能”和“非智能”控制的两种未来能源情景被认为是评估PEC的价值以及相关的投资回收期。结果表明,PVC可以有效地补充BESS对EFR的规定,在未来的GB电力系统。

英文摘要:

The need for Enhanced Frequency Response (EFR) is expected to increase significantly in future low-carbon Great Britain (GB) power system. One way to provide EFR is to use power electronic compensators (PECs) for point-of-load voltage control (PVC) to exploit the voltage dependence of loads. This paper investigates the techno-economic feasibility of such technology in future GB power system by quantifying the total EFR obtainable through deploying PVC in the urban domestic sector, the investment cost of the installment and the economic and environmental benefits of using PVC. The quantification is based on a stochastic domestic demand model and generic medium and low-voltage distribution networks for the urban areas of GB and a stochastic unit commitment (SUC) model with constraints for secure post-fault frequency evolution is used for the value assessment. Two future energy scenarios in the backdrop of 2030 with `smart' and `non-smart' control of electric vehicles and heat pumps, under different levels of penetration of battery energy storage system (BESS) are considered to assess the value of PEC, as well as the associated payback period. It is demonstrated that PVC could effectively complement BESS towards EFR provision in future GB power system.
