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:

Primary Healthcare Centres (PHCs) remain the populations' first point of contact when seeking medical help. Women and children, whose health status decides the fate of the country, are the predominant users of primary healthcare centres which means they (the PHCs') must function as high quality health providers. Karshi Primary Healthcare Centre (KPHC) is one of the health facility that need reliable electricity to improve their healthcare delivery. Due to unreliable power supply, they rely on a diesel powered solution as a primary source of power supply. This negatively impacts patients and th

Electrical generation, 938 Mw, now predominantly (62%) from coal with hydro- at 29% and oil and natural gas at 9%, is expected to grow to 255,000 Mw by the year 2000. Coal will contribute 67%, oil and gas 4%, hydro- 27% and nuclear 2%. There are small, local sources of energy for power generation: geothermal, tidal and wind. Development will be affected by the availability of resources and the extent to which foreign participation is sought.

Renewable energy sources generate power in a variable manner, and there may be unacceptably large fluctuations. Therefore, renewable energy is currently stored in batteries or super capacitors for later use, but this requires expensive maintenance. Therefore, the primary goal of the proposed system is to control renewable energy during fluctuations to provide a continuous power supply. To achieve this, we continuously monitor the solar panel's power generation and load usage, and we send these data to a machine learning model to categorize the switching status of the regulator circuit.

Global demand for primary fossil energy continues to increase. However, the production of energy from fossil fuels, in addition to depleting available reserves, releases millions of tons of Greenhouse Gas (GHG) into the atmosphere. Thus, it is obvious that the high concentration of GHGs in the air disrupts the natural greenhouse effect and consequently causes global warming.

Abstract:

Currently, the usable energy is basically harvested from the fossil energy sources, including coal, oil, and gas, which are believed to harm the environment due to the emitted GHGs. The awareness to the climate change and limited reserve of fossil energy sources has led to a strong motivation to develop a new energy system which can facilitate three important pillars: security, clean environment, and economic opportunity. This future energy system is strongly expected to be able to blend both fossil and renewable energy sources, while minimize its environmental impacts. To realize it, the prim

Abstract:

Abstract Energy is one of the needs to support daily human activities. Without energy, various activities such as industry, health, and household will be disrupted. Total energy consumption in Indonesia in 2018 reached 875 million barrels of oil equivalent (BOE), which was dominated by fuel oil. It illustrates that national energy consumption is still dominated by primary energy sources originating from fossil fuels. Various previous studies have suggested the environmental and health impacts of air pollution from burning fossil fuels. This article will briefly discuss biomass as a primary ene

Abstract:

This paper proposes an intelligent energy management system based on multiple renewable energy sources. The intelligent energy management system is defined as a flexible energy management system built by integrating multiple renewable energy sources and facilities for energy storage. The general objective of this paper is to propose a solution to increase the use of energy potential from renewable sources by embedding small-sized energy sources to behave as a higher-power energy source. The proposed system includes solar, wind, and hydro as renewable sources. As the system is not connected to

Abstract:

Forecasting electricity consumption is a very important issue for governments and electricity related foundations of public sector. Recently, Grey Modelling (GM (1,1)) has been used to forecast electricity demand successfully. GM (1,1) is useful when the observed data is limited, and it does not require any preliminary information about the data distribution. However, the original form of GM (1,1) needs some improvements in order to use for time series, which exhibit seasonality. In this study, a grey forecasting model which is called SGM (1,1) is proposed to give the forecasting ability to th

Abstract:

Microwave fine structures allow us to study plasma evolution in an energy release region. The Siberian Solar Radio Telescope (SSRT) is a unique instrument designed to examine fine structures at 5.7 GHz. A complex analysis of data from RATAN-600, 4–8 GHz spectropolarimeter, and SSRT, simultaneously with EUV data, made it possible to localize sources of III type microwave bursts in August 10, 2011 event within the entire frequency band of burst occurrence, as well as to determine the most probable region of primary energy release. To localize sources of III type bursts from RATAN-600 data, an or

Abstract In the context of this study, we leverage a hierarchical deep reinforcement learning algorithm to address challenges in the integration of renewable energy sources within smart grid environments. The primary focus is on enhancing the efficiency of large-scale renewable energy integration while ensuring grid stability and reliability. The algorithm builds on the principles of hierarchical deep reinforcement learning, aiming to optimize energy utilization, reduce operational costs, and decrease reliance on conventional energy sources within the smart grid framework.

Abstract:

Technology improvement related to energy conservation and energy mix low-carbonization is a critical approach for tackling global warming in China. Therefore, we attempt to identify the technology factors of China’s energy consumption change between 2007 and 2012, when China’s economy started slowing. This study proposes a new refined structural decomposition analysis (SDA) based on a hybrid multi-regional input–output (MRIO) model. The technology factors are expressed through the energy input level effect, energy composition effect, and non-energy input effect. We find that the energy level e
