Heuristic control of discrete power systems

Abstract

The heuristic management of discrete energy systems is considered, which is based on the objective function of the optimization solution of the problem for the heat supply system with a variable structure of technical means. The objective function combines such properties as the quality of the process, the efficiency of the equipment, its reliability and the cost of resources, which allows you to comprehensively evaluate the process of functioning of the system on the basis of technical and economic indicators with restrictions on resources and to determine the best solution in case of their change. The basis of the mathematical model for ensuring the control of the heat supply system by choosing the structure of the control object is the use of a genetic algorithm, which allows achieving rational use of energy resources and minimizing calculation time. Three control algorithms for finding the optimal solution are proposed. A comprehensive criterion for optimal management of the system structure based on technical and economic indicators is proposed. Several variants of control algorithms have been developed that determine the optimal structure of technical means using a genetic algorithm. Each of the options has its own characteristics. If in the first option relay control of the equipment is implemented and the introduction of restrictions on resources and the value of the weighting factors of the control criterion is carried out by the operator, then in the second option their value is automatically estimated based on the availability of energy resources, taking into account their future receipts, as well as unforeseen events affecting the operation of the system heat supply In the third option, during the execution of control according to a previously calculated plan, the calculation of the next plan is carried out in parallel, taking into account the change in the capacity of the equipment. In order to reduce the number of equipment switches while optimizing the system structure, a fourth algorithm was developed, in which control is carried out not only by changing the system structure, but also by changing the tasks of heat transfer technical means regulators.
