摘要：

With the continuous development of new energy technology, the proportion of new energy in the power system is increasing, the amount of power electronic equipment is increasing, and a new power system is gradually formed. In the process of continuous improvement of the new power system, different structures and models have emerged from the traditional power system, which face severe challenges in terms of economy, technology and stability. First, on the power supply side, the proportion of diversified clean energy in the system increases and becomes the main body. Secondly, on the power grid side, a local area network structure is added on the basis of the original large power grid, and on the load side, a multi-energy complementation is gradually formed, and the pattern of interactive development of source and load is formed. Finally, energy storage will become an indispensable element of the new power system. The traditional evaluation system can no longer be used to evaluate the new power system. In order to accurately evaluate the “source, network, load and storage” system, this paper has compiled a set of evaluation index system, which takes into account the factors including economy, reliability, energy utilization.The technical and environmental aspects are included, and the physical meaning and mathematical model of each indicator are analyzed in detail. At the same time, several comprehensive methods for evaluation are introduced in detail, and their applicable scenarios are given. © 2022 Science Press. All rights reserved.
