Power-to-gas Considered Peak Load Shifting Research for Integrated Electricity and Natural-gas Energy Systems
摘要
Abstract
As an important form of the future energy utilization,integrated electricity and natural-gas energy systems is also threatened by renewable energy with high penetration.The power-to-gas (P2G) technique,which has the properties of energy conversion and space-time translation,provides an effective way for renewable energy accommodation and peak load shifting.This paper proposed a peak load shifting model to smooth the net load curve of integrated electricity and natural-gas energy systems by coordinating effect of P2G and gas-fired generators.This model took the economy of the system operation into account simultaneously.The integrated system of the modified IEEE39-node electric network and the Belgian 20-node gas network was accommodated for the test case.The effectiveness of P2G and the proposed model had been verified by analyzing and comparing the ability of wind power accommodation,net load fluctuations and system operation cost in four scenarios.P2G and the proposed peak load shifting model can effectively restrain the net load fluctuations and increase the ability of wind power accommodation.Finally,the effect of economy coefficient on peak load shifting had been further analyzed.关键词
