Optimizing the renewable and fossil-fired generation capacities: Case study of interconnected district-level systems

We first comprehensively analyze determining the generating capacities of each type, then discuss the heat distribution across interconnected district-level heat energy systems (“the hubs”) containing both low-scale and centralized heat plants; discussion is presented from the standpoint of primary...
