    摘 要:熱電聯產(CHP)機組作為綜合能源系統(IES)的關鍵組成部分,其“以熱定電”的特點,嚴重影響了 IES 對新能源的消納能力和低碳運行的經濟性。引入電轉氣(P2G)和碳捕集系統(CCS),將 CHP 機組改造為氣-熱-電聯產(CGHP)機組,并引入了有機朗肯循環(huán)(ORC)對 P2G 過程中的化學熱進行回收利用;對 CGHP 機組的氣-熱-電運行特性進行了研究和分析,在負荷側引入了綜合需求響應(IDR)機制,以配合源側 CGHP 系統進行源荷協同調度。通過仿真驗證了所提出模型及協同運行策略在促進 IES 消納新能源、降低碳排放和總運營成本方面的有效性。

    Abstract: As a key component of integrated energy system (IES), combined heat and power (CHP) units are characterized by“heat to power”, which seriously affects IES’ability to absorb new energy and the economy of low-carbon operation. To solve this problem, this study introduced power-to-gas (P2G) and carbon capture and storage (CCS) devices, converted the CHP unit into a combined gas, heat and power (CGHP) unit, and introduced an organic Rankine cycle (ORC) to recycle the chemical heat in the P2G process. Meanwhile, the gas,heat and power operation characteristics of the CGHP unit were studied and analyzed, and the integrated demand response (IDR) mechanism was introduced on the load side to cooperate with the source-load CGHP system for source-load cooperative scheduling. Finally, the effectiveness of the proposed system model as well as the synergistic operation strategy in promoting the IES to consume new energy and reducing carbon emission and total operation cost was verified through simulation.
    Key words: power-to-gas; carbon capture and storage; combined gas, heat and power; integrated demand response; integrated energy system
