Fuel Saving And Electric Power Quality Improvement In Autonomous Power Supply Systems By Using Energy Storages

Abstract

In autonomous power supply systems for diesel power stations located in remote areas, the main component of costs is the cost of imported fuel. The use of energy storage systems reduces fuel consumption for an autonomous power station. Reducing the northern import of liquid fuel is a relevant task for Russia. The organization of the charge-discharge process of an energy system storage according to the criterion of the minimum daily fuel consumption depends on both the load schedule and the type of flow rate characteristic of the primary engine. When making design and investment decisions on the feasibility of using alternative technical solutions for the modernization of sources in isolated energy supply systems, a comparative assessment of their economic efficiency is necessary. The paper studies the choice of energy storage system power in terms of fuel economy, reducing the installed capacity of a power station for electric power supply systems.
