Methods and Models of Optimal Control of Heat Supply Systems with Prosumers
The paper considers two problem in the framework of researches the prosumers in district heating systems. The first problem is the load distribution in the district heating systems with prosumers. The research suggests a bi-level model for solving this problem to determine an optimal balance between the load of district heat sources and prosumer-owned heat sources. The second problem is the reliability ensuring of heating to consumers through the optimal distribution of reliability parameters among components of system, considering the capabilities of the prosumer to supply part of load by their heat sources. The methods and models are suggested to solve this problem. They are based on the theory of random processes, theory of hydraulic circuits and basic laws of cogeneration. The case study results obtained by using the developed methodology are presented. A potential economic benefit and reliability effect of involving the prosumer is demonstrated in the case study. The conclusions and directions for further research are formulated.
