Coordinating and valuing the flexibility resources in a rural integrated energy system by considering correlated source-load uncertainty

This paper proposes a two-stage model for flexible resource coordination and value analysis in rural areas, which considers the specific biomass energy conversion supply and the correlated uncertainties on both sides of the integrated energy system. Firstly, it describes the impacts of correlated uncertainty on the actual output of the source and load based on factor analysis and affine variables, and constructs an affine optimization model for cooperative scheduling of system-wide flexible resources. Secondly, according to the energy supply envelope area of flexible resources within the scheduling cycle, it proposes the value measurement indices of system flexibility adjustment ability and economic benefit to evaluate the sensitivity of flexible resources. Finally, the simulation results show that the proposed method can effectively reduce the conservatism of the scheduling scheme, and analyzing the influence of capacities and time-of-use tariff on flexibility value provides a reference for the construction of integrated energy systems in rural areas. © 2024
