....046 The paper deals with the actual problem of the functioning and development of district heating systems in the framework of the transition to intelligent energy, in which the active consumers (prosumers) holds the key place. The paper proposes an optimization mathematical model for management the operation of district heating systems taking into account prosumers based on the bi-level modeling method (bi-level programming). The proposed mathematical model allows taking into account the technical ...
