摘要
Abstract
The growing share of renewable energy leads to increased load volatility and uncertainty in power system,necessitating greater flexibility in cogeneration systems.The utilization of molten salt thermal storage equipment can enhance the performance of cogeneration systems.Against the main-pipeline cogeneration system consisting of four boilers and two steam turbines which is integrated with a coupled molten salt thermal storage equipment,the EBSILON simulation software is used to establish mechanism model for power supply and heating.The influence of molten salt heat storage equipment on combined heat and power system performance is analyzed,and the optimization scheduling methods for coupled systems are also investigated.The results show that,the coupling of molten salt thermal storage equipment in cogeneration systems can increase the system's peak shaving capacity,expand the system's operating range,and broaden the unit's operating area.After estimation,the amount of coal saved in one day can be about 4.16 tons,the carbon emissions can be reduced by about 8.25 tons,and the pollutant emissions can be decreased by about 1.76 kg.The molten salt thermal storage equipment has improved the system's economy and environmental friendliness.关键词
