Methodological Approach to the Integrated Optimization of the Heat-Source Structure in the Problems of Developing Heat-Supply Systems

An Approach for Efficient Heat Source Selection in Long-Term Expansion Planning of Urban District Heating Systems

“…eps out S -the tariff for selling electricity to the power system; eps in W -the amount of electricity purchased from the power system; eps out W -the amount of electricity sold to the power system. The objective function ( 4) is specified together with a number of constraints on meeting heat and electricity balances, the amounts of fuel burned, the conditions of competition between alternatives, and compliance with pollution limits induced by regulators, as detailed in [16].…”

“…Fitness evaluation is the task of Stage 2 (Fig. 1), at this stage we use the model developed previously by the authors to determine the optimal HS structures in the DHS, which is based on generating and optimizing redundant layouts [16].…”

“…Previously, the authors [16] proposed and formalized the problem of determining the optimal mix of HS equipment for the tasks of DHS expansion planning. It uses such a technique to represent the solution space in the form of a redundant designed layout (superstructure).…”
