Abstract:

The subject of the present research is the assessment of access of residents of Northern cities to energy produced from renewable energy sources (RES). The largest Arctic cities in Russia, Sweden, Norway, Finland, Denmark, the USA and Canada, located above 66 ° 33 ´ North latitude, are analysed. The importance of the study is due to the categorisation of access to RES as a fundamental good in the context of Sustainable Development Goals and fight against climate change. The work uses the index method, followed by ranking cities by the level of access to energy from RES. The following variables

Abstract:

Global economic growth is accompanied by increased energy demand, thus conventional fuels such as coal, oil and gas, which are the primary energy sources, are gradually being depleted. At the same time, the combustion of conventional fuel for energy production causes serious adverse effects on the environment and contributes to climate change due to the emitted greenhouse gases. For the above reasons, most of the developed and developing countries especially during the last decades, have introduced various incentives for the greater penetration of renewable energy sources (RES) in all sectors

Abstract The problem of global warming is a problem facing the world community. Since the Industrial Revolution’s birth, the use of energy from fuel oil (FF) has surged, and this causes an increase in Greenhouse Gases (GHGs) resulting from burning fuel. This GHG is the cause of the rise in the earth’s temperature, which is estimated to one day, the earth is not comfortable and even no longer habitable. The solution to the problem is reducing GHGs that can be done by saving fuel use, which is replaced with renewable energy sources (REs). RE sources are obtained from the Solar Power Plant (SPP),

Renewable Energy Sources are considered a strategic factor, due to their weight to the green power production and also to the important role they play to the economic aticity as a whole. These explicit relationship between the power sector and the economy address some questions about the impact of the power sector transformation in the Albania’s economy. These study’s purpose is to give a qualitative and empirical presentation of the renewable energy sources, having into focus the power sector development, the potential of the green energy production and the creation of the competitive advanta

Abstract:

A key focus of the Sustainable Development Goals (SDGs) is to harvest electricity from renewables. The fields of renewable energy sources (RES) and harvesting methods have seen tremendous growth. Multiport power electronic converter circuits integrate multiple energy sources. This integration aids in powering the load with different required voltage ratings. A simple and reliable control scheme for this system can maintain high power transfer efficiency and reliability. To integrate RES, non-isolated (NI) DC-DC multiport converters (MPC) are introduced; however, the main objective is to concen

Electric energy supply of cities with dense buildings is provided mainly from centralized generation sources: TPPs, CHPs, NPPs, RES, and heat energy - from CHPs and gas boilers. Possibilities of energy self-sufficiency of Ukrainian cities based on use of alternative and local energy sources are analyzed. There is a global trend of increasing share of RES in cities energy supply, especially in cities and districts with cottage development.

Abstract:

This paper presents a multiagent system (MAS) day-ahead co-operation framework between renewable energy resources (RESs) and Battery Energy Storage Systems (BESSs) owned by different stakeholders. BESSs offer their storage services to RESs by shifting RES power to sell it during profitable peak-hours (aka; time-shifting). The MAS framework consists of three phases. Phase-one is a pre-auction phase that defines the maximum charging and discharging BESS power limits. These limits guarantee a reliable distribution system operation without violating the buses’ voltage limits or the ampacity of the

This paper presents a method for refining the forecast schedule of renewable energy sources (RES) generation by its intraday adjustment and investigates the measures for reserving RES with unstable generation in electric power systems (EPSs). Owing to the dependence of electricity generation by solar and wind power plants (PV and WPPs, respectively) on natural conditions, problems arise with their contribution to the process of balancing the power system. Therefore, the EPS is obliged to keep a power reserve to compensate for deviations in RES from the planned generation amount. A system-wide

Multilevel inverters are vastly used in power systems and “renewable energy sources” (RES) to provide an AC voltage with a low level of harmonic contents. This paper aims to design a 9-level inverter for RES such as photovoltaic (PV), wind turbines, and fuel cells… etc. The proposed inverter is constructed by 12 IGBT switching devices where all of which are powered by 4 DC sources of 81 V without balancing capacitors to make DC voltage 324 V. A Phase disposition (PD), alternative phase opposition disposition (APOD), and POD with a slight phase shift are the methods of modulations that are used
