Оптимальное управление структурой и эксплуатационными режимами интегрированных энергетических систем

Abstract

Background: At present, a lot of attention is paid to the optimal load distribution between the thermal power plant units, on the one hand, and, within the concept of «smart grids», to the optimal transportation of energy from the supplier to consumers, on the other hand. And the problems of optimal generation and optimal transport of energy are considered separately, although energy generation and transmission processes are closely related to each other. A joint analysis of the generation and transport will allow getting an additional effect from optimization that cannot be achieved by separate consideration of these processes. Thus, the joint analysis of the generation and transmission of energy in order to minimize the total costs of energy resources at a given energy supply of consumers is a current research priority. Materials and methods: The power equipment models were constructed based on the energy characteristics of the units, while the formulation of and solution to the optimization problem is based on the approaches and mathematical programming techniques. Results: The paper formulates a problem of optimal energy generation and transport in inter-related thermal and electric networks in order to obtain the minimum energy costs for the given power consumption. It also describes a solution to the optimization problem, in which the optimal load of generating units and optimal transport of energy flows in the system are found. Conclusions: The proposed approach ensures energy supply to consumers at the minimum resource cost. This solution is a prerequisite for the creation of intelligent energy-saving systems, that allow online maintenance of the given energy supply with the minimum total cost of energy resources.
