ANALYSIS OF ENERGY EXCHANGE PROCESSES WHEN BALANCING REGIMES ENERGY SUPPLY SYSTEMS WITH DISTRIBUTED GENERATION

Abstract

It is shown that maintaining a balance between the production and consumption of electric energy is an important condition for the stable operation of modern energy supply systems. The active increase in the share of renewable energy sources forces the use of new algorithms for balancing demand and supply, in particular, at the expense of flexibility. This implies the need to implement new technological solutions and approaches to balancing the modes of generation and consumption (the ability to quickly respond to changes in demand and supply), which, in turn, requires a detailed analysis of energy exchange processes in electric power systems.
 It is recognized that there is a need for an in-depth analysis of the balance of energy components, and an assessment of electromagnetic compatibility in electric power systems, especially in the conditions of the growing influence of renewable energy sources on local electricity markets. Analysis of various factors influencing technological solutions and cooperation of different market parties are key components for developing effective management strategies and ensuring the stability of the electric power system.
 The peculiarities of the analysis of energy exchange processes in local electric power systems with the determination of exchange capacities, which are integral characteristics of the influence of various factors of the non-acidity of electricity on exchange processes, are considered. It is proposed to balance the components of electric energy on the basis of exchange processes in controlled intersections of local electric power systems using the components of instantaneous power at each energetically constant state. The exchange processes in local electric power systems are analyzed with the selection of different modes of their operation, in particular, when assessing the level of electromagnetic compatibility of the elements of the local electric power systems.
 The introduction of exchange capacities made it possible to develop indicators for assessing the level of electromagnetic compatibility of the elements of the local system. To estimate the share of consumers' contribution to the deterioration of the quality of electricity at the common connection point, an algorithm for evaluating the mutual influence of elements is proposed, with the allocation of the element's contribution to the distortion of electricity in the controlled intersection and the analysis of the magnitude of the influence of distorting factors on electromagnetic processes in the system element.
 An optimization model for achieving the specified levels of balancing (flexibility) in local electric power systems with energy accumulators has been developed.
