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.

Highlights

The use of energy storage systems (ESS) may be appropriate for diesel-generator units, primarily diesel fuel, gasoline, fuel oil, as their operation is associated with the need for constant delivery of fuel and its seasonal storage, with the need to work in intermittent modes following the load of consumers, which significantly increases fuel consumption, and, current costs [1,2,3]
It is possible to note that the General Electric Corporation and the California-based energy company Southern California Edison announced the implementation of the first project in the world of a hybrid power station in which a gas turbine unit (GTU) works in conjunction with ESS [4,5,6]
Such an application will provide a solution to such problems as: - increasing the limits of the dynamic stability of GTU with small values of the moments of inertia during accidents in the grid; Research is made with financial support of the Ministry of Education and Science of the Russian Federation within implementation of the federal special program «Research and development in the priority directions of scientific and technological complex of Russia for 2014-2020», the agreement on granting a subsidy No 075-15-2019-057, unique identifier of applied scientific research RFMEFI57418X0188

Summary

Introduction

The use of energy storage systems (ESS) may be appropriate for diesel-generator units, primarily diesel fuel, gasoline, fuel oil, as their operation is associated with the need for constant delivery of fuel and its seasonal storage, with the need to work in intermittent modes following the load of consumers, which significantly increases fuel consumption, and, current costs [1,2,3]. The determining criteria for the selection of power units for use in an autonomous power supply system (APSS) are fuel consumption issues, the level of operating costs, and the payback period of power station equipment.
