摘要
电压暂降的有效治理对于用户、电网及所在区域均为有利,比较治理电压暂降多种模式的投融资经济性评估具有实际应用价值。在此背景下,首先在用户自承担治理模式中提出以用户性价比最高为目标的优化配置模型;其次在服务费治理模式中提出多重考虑因素的租金模型;然后在PPPO&M模式中引入成本控制因素优化租金模型,基于引入政府方投资的PPP模式纳入区域经济效益与区域环境效益优化投资模型;最后以4种模式为基础,探讨不同治理模式的经济性评估,并在IEEE 30系统中进行仿真模拟,计算各方在各个模型中的净现值,内部收益率及投资回报周期,比较多种模式在同一条件下的经济性。
Effective management of voltage sag is beneficial to users,power grids and the region where it is located.Comparing the investment and financing economic evaluation of various modes of voltage sag treatment has practical application value.This paper firstly proposes an optimal configuration model aiming at the highest cost-effectiveness for users in the user self-pay governance model.Secondly,a rental model is presented with multiple considerations in the service fee governance model.Then,the cost control factor is introduced into the PPPO&M model to optimize the rent model.The PPP model based on the introduction of government investment is incorporated into the regional economic benefit and regional environmental benefit optimization investment model.Finally,based on the four models,the economic evaluation of different governance models is discussed.Simulation is carried out in the IEEE 30 system to calculate the net present value,internal rate of return and investment return period of all parties in each model and compare the economics of multiply models under the same conditions.
