Влияние режимов работы гибридных энергетических комплексов на основе возобновляемых источников энергии на определение типа аккумуляторов энергии

Abstract

The aim of the work is to study the performance characteristics of generating units operating on the basis of renewable energy sources (RES) as part of a hybrid energy complex and to determine the requirements posed by these generating units to the storage systems in terms of stored energy amounts and power absorption and delivering conditions on long, medium and short intervals of time. Using the data from a real consumer located on Popov Island, the relevant energy complexes were modeled, and their operating modes were calculated and analyzed. The technical requirements posed by the RES-based installations to the performance characteristics of energy storage devices in terms of stored energy amounts and power absorption and delivering conditions on different time intervals are determined. The obtained results are important for elaborating efficient energy storage systems for RES-based hybrid energy complexes for improving their reliability and technical and economic efficiency. It has been established, based on the calculations and analysis of the RES-based hybrid energy complex operation modes, that for meeting the hybrid energy complex requirements, the complex should be fitted with a hybrid energy storage system combining various sources of electrical energy. Some of them, in view of their high energy capacity (e.g., hydrogen electric energy storage devices), can be considered as energy sources for seasonal and daily regulation, and others (supercapacitors) can be regarded as power sources to be used in the modes of absorbing and delivering power pulses on second time intervals.
