| Abstract: |
| Accurately obtaining the state parameters of energy and exergy is one of the essential prerequisites for achieving the coordinated development of quantity and quality in integrated energy system. Traditional state estimation of integrated energy system provides crucial support for their energy management system from the perspective of multiple energy flows. Building on this foundation, to realize the coordinated operation of quantity and quality in integrated energy system, the concept of a future energy and exergy management system of integrated energy system(IES-E2MS) is described. It highlights the necessity of energy and exergy state estimation of integrated energy system(IES-E2SE). Based on the steady-state model of energy flow and exergy flow in integrated energy system, an IES-E2SE method is proposed. This method achieves the coordinated estimation of energy flow parameters and exergy flow parameters by integrating existing traditional measurement configurations, laying a foundation for advanced analysis applications of coordinated quantity and quality. Through a 12-bus test case and a 120-bus practical engineering case, the reasonableness and applicability of the proposed method are validated, and the development of IES-E2SE is forecasted. |
