Integration of optimal combinations of renewable energy sources into the energy supply of Wang-An Island

Abstract. The issues of modern urban development raise a significant question about an environmental cleanliness of progressing cities. Energy sources which are running on fuel cause tremendous harm to the atmosphere. Therefore, special attention is paid to the rational use of natural renewable resources such as wind and solar energy. Wind-electric sets, or wind turbines, are able to work autonomously, which is also important for the development of modern "smart" cities. Currently, the most commonly used design of wind turbines is the system which has the form of a tower of circular cross section (also called pipe), which carries at the upper end a nacelle with wind wheel. When such a system is being designed in urban conditions the wind pulsation and seismic calculations are added to the standard calculations. These added calculations are dynamic loads. It is known that in the process of solution of dynamic tasks design models of various levels of approximation can be used. It occurs due to stages of the design and other factors. The question of errors, which are associated with the use of a dissected, or partitioned, design scheme, raises.

“…Concern about the fact that production of energy from renewable sources is not constant and does not satisfy energy demand, has prevented many countries from integrating RES into the national energy systems. However, remote islands often provide ideal conditions for a feasibility study and the creation of independent energy systems based on the use of alternative energy sources, due to lower population density, less energy consumption and extensive land or coastal areas not sufficiently involved in economic activities, which enable the use of alternative energy sources [1]. There are more than 50,000 islands in the world, which accounts for 17% of the total land area of the globe [2].…”

“…The solar, wind and energy potential of the Maldives biomass is 9.51 × 10 8 MW [5], which is much more than their annual energy consumption. In the work "Integration of optimal combinations of renewable energy sources into the energy supply of Wang-An Island" [1], a comprehensive study was conducted for Van-Ai Island, located west of Taiwan Island, which includes calculating the energy that can be obtained by wind, sun, waves and biomass, as well as a solution to the problem of the inconstancy of energy production.…”

This paper aims to analyse the current situation of the energy system of the remote island territory of Solovetsky Archipelago. The Solovetsky historical and cultural complex was included in the list of UNESCO World Heritage Sites. Diesel fuel, which is used on the archipelago is expensive and pollutes the environment. By using Computational Fluid Dynamics (CFD) based numerical method, this study aims to determine the wind energy potential of the territory, which will cover part of the energy consumption. For the best use of wind potential, several variants of the location of the wind park were analyzed in this study. Thus, using wind energy, as an alternative source, the amount of emissions of harmful substances will be reduced, which is a priority for the Arctic region.

“…On the basis of this model, in Fiji Islands, a linear regression model to estimate grid-electricity demand was considered [33]. For the energy supply on Wang-An Island, similar rank points were given for identifying the optimal integrated electricity production from RES [34]. The reduction of the CO 2 emission factor will then be indicated at the end of this Section 4.…”

Decarbonisation in the generation of electricity is necessary to reduce fossil fuel consumption, the pollution emitted and to meet the Energy Technology Perspectives 2 • C Scenario (2DS) targets. Small islands are not exempt from this target, so this study's emphasis is placed on a 50-50 target: to reduce the fossil fuel consumption through electricity generation from Renewable Energy Sources (RES) to cover 50% of all electric demand by 2050 on small islands. Using Cozumel Island, Mexico, as a case study, this analysis will be based on three factors: economical, technical, and land-use possibilities of integrating Renewable Energy Technologies (RETs) into the existing electrical grid. This analysis is made through long-term statistical models. A deterministic methodology is used to perform time-series simulations. The selection of the best system was made on the basis of a Dimensional Statistical Variable (DSV) through primary and secondary category rankings. The presented methodology determines the best systems for capturing the initial capital cost and competitiveness of this new proposal compared with the current system of electricity generation on the Island, and can be applied to small islands as well. According to the results, all systems proposed are able to completely satisfy the renewable electricity needed by 2050 in all scenarios. From the 12 system proposals that were compared, two systems, System 2 and System 7, were chosen as eligible systems to be installed. The Levelized Cost of Energy (LCOE) result for System 2 was 0.2518 US$/kWh and for System 7 was 0.2265 US$/kWh by 2018 in the Base Scenario. Meanwhile, the Internal Rate of Return (IRR) value fluctuated from 17.2% for System 2 to 31% for System 7.
