Abstract

Test results of the main industrial prototype of energy storage system (ESS-10-1200-400) of nominal power 1200 kVA, energy capacity 400 kWh and voltage 10 kV based on lithium-ion batteries when operating in combination with gas engine generators (GEG) as a part of experimental power system with active abrupt variable load are given. Its structure, components and parameters, as well as the components and parameters of ESS are described. Tests have shown high operation capacity of the prototype tested, high efficiency of the implemented algorithms and confirmed the expediency of the use of ESS for smoothing power surges/sheddings in the GEG, thus preventing their emergency shutdown resulted from the power surge.

Highlights

At present the technologies of energy storage in Russia have reached the level of common practical application in the electrical power systems
The necessary consideration of these features in the process of GEG operation is especially important, because gas engine generators are widely used at off-grid power plants of oil and gas producing enterprises, the load of which has a pronounced abruptly variable stochastic character
The experimental unit consists of two GEGs, power transformers, sectionalized active load, whose value is discretely changed by switching devices, energy storage system, control and recording equipment, control system

Summary

Background

At present the technologies of energy storage in Russia have reached the level of common practical application in the electrical power systems. The necessary consideration of these features in the process of GEG operation is especially important, because gas engine generators are widely used at off-grid power plants of oil and gas producing enterprises, the load of which has a pronounced abruptly variable stochastic character. This kind of the load, in addition to other negative effects, leads to increased wear of the equipment and, to increased costs for repair and maintenance of gas engine units.
