The purpose of the article is to assess the potential and prospects of using renewable energy sources in order to diversify electricity supply. The object of the study is the natural and economic conditions that determine the feasibility of using renewable energy sources in order to diversify electricity supply. The basis of the study was the data of domestic and foreign scientists in the field of assessing the possibilities of using renewable energy sources. The region of activity of the guaranteeing supplier JSC AtomEnergoSbyt is represented by the Kursk, Smolensk, Tver and Murmansk regions. An assessment of the installed electric power generation capacities made it possible to determine that in the Kursk and Smolensk regions generation with the use of atomic energy predominates. In the Tver region, the largest share of installed capacities is accounted for by nuclear generation, however, thermal generation has a significant share. The installed capacities of the Murmansk region demonstrate significant differentiation. There is generation in the region using atomic, hydrocarbon and renewable energy sources. The region is the only one among the considered regions that uses renewable energy sources. More than half of the generation of electricity in the Murmansk region occurs using renewable energy sources. An assessment of the potential of renewable energy sources in the region of activity of the guaranteeing supplier showed that in the Kursk, Smolensk and Tver regions it is inexpedient to place generation facilities using solar, wind, geothermal and small river energy. In the Murmansk region, on the contrary, there is sufficient potential to accommodate wind and small hydropower plants. An assessment of the bioenergy potential of the livestock industry showed that it is advisable to develop biogas energy in the Kursk, Smolensk and Tver regions, which, on the one hand, will allow the disposal of livestock waste, and, on the other hand, provide small towns with electricity and heat.

Wind Generator

The use of inexhaustible or renewable energy sources (water, wind, solar, Earth heat) is an urgent task both in Russia and in the world. According to expert estimates, the Russian Federation has a large global wind potential. Efficient use of energy resources, including renewable energy sources, is the way to increase the energy efficiency of agricultural production. The share of energy consumption in the total cost of production reaches 32 percent in some industries. In recent years, many new consumers have arised, for whom the choice of a rational energy supply system is important at the design stage. For producers of agricultural products, the problem of the quality of electricity supply is also acute. Taking into account the specifics of agricultural areas, it can be concluded that it is local and renewable energy sources that will help to successfully solve the problems of uninterrupted energy supply and energy conservation. (Research purpose) The research purpose is in assessing the impact of the quality of electricity supply on agricultural production facilities and identifying modern domestic equipment that reduces the risks of using renewable energy sources in agricultural production. (Materials and methods) Author used the calculation and analytical method to evaluate the average indicators of electricity costs at livestock enterprises. The article presents a review of the automated control systems of the wind generator based on the equipment of the Russian manufacturer OWEN. (Results and discussion) Author studied the control system of a wind generator on the example of an installation used in the territory of the agricultural enterprise "Melnikovo" of the Gvardeysky district of the Kaliningrad region. The control system reduces the risks associated with the operation of the wind generator. (Conclusions) This system, which was put into operation in 2019, makes it possible to avoid failures in the operation of the wind generator. Work is underway to develop modern technical solutions for remote recovery of wind turbines, which is important when services are remote.

A 100% renewable electricity supply is no insurmountable technical problem anymore after the respective technologies to harvest the energy from multiple renewable energy sources have been developed and have reached a high level of maturity. A problem may rather be suspected to reside on the economic side of an exclusively renewable electricity supply. The present study examines the economic implications of a renewable energy scenario for the Java-Bali grid. Based on given energy supply scenarios, the costs of an electricity supply from renewable energy sources alone are determined. Economic optimum configurations are determined for which the annual system costs and accordingly the power generation costs are minimized. First the system running costs are considered, i.e. the operation and maintenance costs as well as the costs of the continuous renovation of system components, while capital costs are not taken into account. After this the capital costs are taken into consideration, and total system costs and power generation costs are determined. The main result is a specification of economic optimum system configurations. One important result is that a future electricity supply from renewable resources alone is not more expensive than the current power generation in developed countries. Another result is that the integration of special long-term storage into the Java-Bali grid, like for instance methane storages, besides pumped storages and batteries, is not economically favourable if further moderate battery cost reductions are reached.Article History: Received May 18th 2018; Received in revised form August 16th 2018; Accepted October 1st 2018; Available onlineHow to Cite This Article: Günther, M., Eichinger, M., (2018) Cost Optimization for the 100% Renewable Electricity Scenario for the Java-Bali Grid, International Journal of Renewable Energi Development, 7(3), 269-276.https://doi.org/10.14710/ijred.7.3.269-276

Demand And Supply

An equilibrium economic model for policy evaluation related to electricity generation has been developed; the model takes into account the non-renewable and renewable energy sources, demand and supply factors and environmental constraints. The non-renewable energy sources include three types of fossil fuels: coal, natural gas and petroleum, and renewable energy sources include nuclear, hydraulic, wind, solar photovoltaic, biomass wood, biomass waste and geothermal. Energy demand sectors include households, industrial manufacturing and commercial enterprises (non-manufacturing businesses such as software firms, banks, restaurants, service organizations, universities, etc.). Energy supply takes into account the electricity delivered to the consumer by the utility companies at a certain price which maybe different for retail and wholesale customers. Environmental risks primarily take into account the CO2 generation from fossil fuels. The model takes into account the employment in various sectors and labor supply and demand. Detailed electricity supply and demand data, electricity cost data, employment data in various sectors and CO2 generation data are collected for a period of seventeen years from 1990 to 2006 in U.S. The model is calibrated for the aggregate data. The calibrated model is then employed for policy analysis experiments if a switch is made in sources of electricity generation, namely from fossil fuels to renewable energy sources. As an example, we consider a switch of 10% of electricity generation from coal to 5% from wind, 3% from solar photovoltaic, 1% from biomass wood and 1% from biomass waste. It should be noted that the cost of electricity generation from different sources is different and is taken into account. The consequences of this switch on supply and demand, employment, wages, and emissions are obtained from the economic model under three scenarios: (1) energy prices are fully regulated, (2) energy prices are fully adjusted with electricity supply fixed, and (3) energy prices and electricity supply both are fully adjusted.

The Cost

The statistical analysis of the forecast error of the "day ahead" electricity supply volumes by the producers, which are included in the balancing group of the State Enterprise "Guaranteed Buyer”, was carried out. The distribution of forecast errors by hours of the day is determined. A simplified method for calculating the price and the total cost of the forecast error is described considering the various formulas for the cost of imbalances calculating. The potential for improving the accuracy of the forecast for increasing the permissible installed capacity of power plants with renewable energy sources with the technical means available in the power system to compensate for the power fluctuations is shown. Approbation of the methodology and calculation of quantitative indicators was carried out on real data of the total supply of renewable energy sources by producers, which were published by SE Energorynok. The calculations are of an estimate nature. Since the calculations are based on a “naive” assumption about the distribution of forecast errors, which depend on the structure of RES producers by types of primary energy carriers and specific meteorological conditions.
