An object of the research is the residential district of Kharkiv city heated by JC Kharkiv CHP-plant #5. A subject of the research is a target value of CHP-plant daily heat output and an hourly schedule of heat carrier temperature for flexing CHP-plant. An objective of the research is to synthesize a mathematical model of Kharkiv CHP-plant #5 heating region and to develop energy-efficient control algorithms for both daily heat output and the hourly schedule of heat carrier temperature that takes into account daily dynamics of heat demand in household. Used research methods are neural networks, genetic algorithms, fuzzy logic and evolutionary simulation. The reliability of proposed heat carrier temperature control algorithms has been proved during experimental study by using independent methods of heating quality control, namely monitoring of surplus dwelling electricity load. There are obtained heat output control algorithms for Kharkiv CHP-plant #5. They provide energy saving by means of cogenerationpower units' heat output reduction during evening and night hours on experimentally estimated value equal to a hot water supply load. The research results are experimentally proved on JC Kharkiv CHP-plant #5 and implemented in projects of enterprise internal standards and "The Temporal procedure of heat carrier parameters concordance between JC Kharkiv CHP-plant #5 and Kharkiv Heating Networks, plc.
