Abstract
The paper presents a developed method for modelling of the possibilities of autonomous electrical energy system operation in remote or rural places including power storage systems and renewable energy sources.The methodology includes analyzing of the potential for renewable energy sources.The energy, produced from the RES can be characterized as variable generation (VG) and this creates certain difficulties for the involvement of RES in the overall generation.Another point is that there can be limited possibilities of the links to the electrical grid in rural regions.There are several options of solving such problem, like: back up power supply with diesel generators and etc.One of the most promising solutions to this problem is creation of power storage facilities.The main purpose of the power storage facility is to smooth out the peaks of electricity generation and consumption.The second purpose is to provide power supply in the case of absence of generation from renewables.The numerical results show the possibilities of autonomous operation of a part of the power system with a certain combination of renewable energy sources and electric power storage, and covering the electricity deficit from the renewables instead of commissioning of traditional energy sources.We show that solving the problem of power supply and cover the electricity deficit in rural places with the help of renewable energy, including power storage systems, can minimize the impact on the environment in rural regions.
