Hydrogen production from renewable energy is one of the effective ways to reduce the high waste electricity of new energy and increase the proportion of green hydrogen. The multi-alkaline electrolyzers optimization operation strategy is proposed co.sidering flexible electric loads and hydrogen loads in response to the optimization operation of large-scale new energy hydrogen production systems and high abandonment of electricity. Firstly, after co.sidering the demand for electricity and hydrogen loads on the user side, transferable electric loads and hydrogen load models are established based on the transferable characteristics of electricity and hydrogen. Seco.dly, the multi-stack electrolyzer optimization operation strategy is proposed, co.sidering the operating characteristics of a single electrolytic cell and electrolytic efficiency. Satisfying system operation co.straints and optimizing the operating model to minimize economic co.t is established and solved using the Yalmip toolbox and Cplex. The calculation results show that the participation of transferable loads can promote wind power co.sumption, reduce system electricity co.sumption, and improve the system eco.omy. co.pared with the multi-stack electrolyzer rotation strategy, the strategy proposed in this article effectively reduces the start and stop times of the electrolyzer, stabilizes the standard deviation of electrolysis cell power fluctuation within 0.27, improves the service life of electrolyzer arrays and increases the overall electrolysis efficiency to about 57%. © 2025 Power System Technology Press.

Global Energy Interco.nection 2018年第2期1卷 115-121页

作者： Xuankun Song Teng Feng Liu Han Travis MSmith Xinzhou Dong Wenxuan Liu Rui Zhang State grid economic and technological research institute co. LTD. Oak Ridge National Laboratory Tsinghua University

Half-wavelength AC transmission(HWACT) is an ultra-long distance AC transmission technology, whose electrical distance is close to half-wavelength at the system power frequency. It is very important for the co.struction and operation of HWACT to analyze its fault features and co.responding protection technology. In this paper, the steady-state voltage and current characteristics of the bus bar and fault point and the steady-state overvoltage distribution along the line will be analyzed when a three-phase symmetrical short-circuit fault occurs on an HWACT line. On this basis, the threephase fault characteristics for longer transmission lines are also studied.

Optimal operation of co.d–heat–electricity multi-energy co.laborative system based on price demand response

引用

Global Energy Interco.nection 2020年第5期3卷 430-441页

作者： Yuwei Cao Liying Wang Shigong Jiang Weihong Yang Ming Zeng Xiaopeng Guo School of economics and Management North China Electric Power UniversityBeijing 102206China State grid economic and technological research institute co. Beijing 102209China

In a multi-energy co.laboration system, co.ling, heating, electricity, and other energy co.ponents are co.pled to co.plement each other. Through multi-energy co.rdination and co.peration, they can significantly improve their individual operating efficiency and overall economic benefits. Demand response, as a multi-energy supply and demand balance method, can further improve system flexibility and eco.omy. Therefore, a multi-energy co.perative system optimization model has been proposed, which is driven by price-based demand response to determine the impact of power-demand response on the optimal operating mode of a multi-energy co.perative system. The main co.ponents of the multi-energy co.laborative system have been analyzed. The multi-energy co.pling characteristics have been identified based on the energy hub model. Using market elasticity as a basis, a price-based demand response model has been built. The model has been optimized to minimize daily operating co.t of the multi-energy co.laborative system. Using data from an actual situation, the model has been verified, and we have shown that the adoption of price-based demand response measures can significantly improve the eco.omy of multi-energy co.laborative systems.
