Abstract
Developing of new technologies such as electrical energy storage systems (EESS) opens new ways to increasing efficiency, decreasing exhaust waste and fuel consumption in traditional fossil fuels power station. This paper contains actual testing results of electrical energy storage system based on lithium-ion technology working with gas engine generator and altering load power. EESS parameters: rated power 100 kVA, rated capacity 153 kWh. As is known, gas generators are sensitive to changes in load power, obtained results show the effectiveness of the usage EESS to supply sustainability of generators in high amplitude and frequency altering load power environment. These results achieved through the ability of the developed converter and control strategy to compensate rapid deviations of the load power. In additional, in control system realized others common functionality: active power limitation, voltage and frequency control, reactive power control, power factor control and others. With the usage EESS, the nominal power of plane station should be lower than without EESS.
Highlights
The global interest in reducing the volume of hydrocarbons burned caused a spread interest in the using of renewable generation at the electric power industries of most developed countries. This type of generation is not able to completely displace the traditional power stations because of its operation peculiarities, namely of the stochasticity of the generated power. This peculiarity allowed the development of a whole class of devices, which are commonly referred to as electrical energy storage systems
The development of electrical energy storage systems is due to the spread of electronic portable devices and electric transport, these industries have increased the specific capacity of batteries and reduce the cost of their production
At the moment it is too early to discuss about large-scale application of electrical energy storage systems to increase the efficiency of electricity generation, which is associated with their high cost, the application in local isolated power systems is a promising direction and it possible to improve the efficiency of traditional power plants
Summary
The global interest in reducing the volume of hydrocarbons burned caused a spread interest in the using of renewable generation (mainly solar power and wind power) at the electric power industries of most developed countries. This type of generation is not able to completely displace the traditional power stations because of its operation peculiarities, namely of the stochasticity of the generated power. This peculiarity allowed the development of a whole class of devices, which are commonly referred to as electrical energy storage systems.
