Abstract

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.
