Optimal Scheduling of Pumped Storage in Power System with Large-scale Photovoltaic Based on Carbon Emissions Trading

Abstract

In order to improve the photovoltaic penetration of the power system, an optimal scheduling model of pumped storage system with large-scale photovoltaic based on carbon trading is proposed in this paper. Firstly, based on the analysis of low-carbon economy, the stepped carbon emission trading mechanism is introduced into the economic dispatch of power system. And in order to improve the calculating efficiency, an improved K-means clustering algorithm based on maximum and minimum distance criterion is proposed to cluster the photovoltaic power generation scenarios. Then the optimal scheduling model is established. Take the lowest comprehensive operation costs of the system as the objective function, and the operation economy and low carbon of the system are considered. The pumped storage is used as energy storage for peak load shaving in the generation system. At last, an improved IEEE RTS-96 system is taken to finish the case study, and the simulation results show that the model proposed in this paper is reasonable and effective.

Empirical Analysis of the Carbon Accounting Information Disclosure (CAID) Affecting R&D Investment and Sustainable Development in State-Owned and Non-State-Owned Enterprises

“…In February 2021, China stated that it will gradually promote the realization of highefficiency and high-quality environmental protection and establish a new system for China's economic development to ensure the achievement of the carbon peak and carbon neutrality goals. According to the relevant deployment, China is striving to achieve the carbon peak by 2028 [4]. It must be said that carbon accounting is an important component of achieving carbon peaking and carbon neutrality.…”
