Abstract:

ABSTRACT Renewable energies are alternatives to replace fossil fuels and are crucial for the sustainability of the agricultural sector, besides being an important alternative for pumping water in irrigation. Thus, understanding revenues and expenses is fundamental in economic feasibility. Therefore, the aim of this study was to assess the behavior of economic indicators in off-grid solar energy system for irrigation based on different scenarios. Photovoltaic projects were developed for different irrigation powers ranging from 0.736 to 22.1 kW, and the costs for implementation and operation, as

Abstract:

A photovoltaic (PV)/wind/battery/Generator-Set hybrid power system's energy dispatch is discussed in this research, along with the ideal solution. The optimization model enables the hybrid power system's generating devices to share power appropriately. The main goals are to minimize fuel consumption and costs and maximize the usage of Renewable Energy Sources (RES). The proposed simulation plan succeeds in lowering fuel costs because the diesel generator only kicks on at night and in the early morning when the energy from RES is insufficient to supply the load. The load is supplied with power,

Abstract:

It is critical to increase the value of life in rural areas by developing power from renewable sources or expanding the grid. The extension of the national grid or off-grid systems depends on location, geography, population, distance from grid point, and land size. Since grid connections are not always available or feasible, off-grid rural electrification systems using renewable energy sources (RES) have become unavoidable. An alternative to costly grid extensions in remote areas of the world is a hybrid combination of renewable energy technologies. This review paper discusses renewable energy

The study examines two different PV system configurations: On-Grid PV and Off-Grid PV, using sophisticated simulation and analytical techniques with the aid of HOMER Pro software. The simulation results offer compelling new information about these systems' economic viability. The simulation results in an NPC value of IDR 31,386,360,- for the Off-Grid PV configuration. The On-Grid PV system, in contrast, exhibits a sign

Abstract:

Pembangkit listrik tenaga surya (PLTS) merupakan salah satu sistem alternatif yang berasal dari energi matahari yang dapat digunakan untuk mensuplai kebutuhan energi listrik rumah tangga. Saat ini, kebanyakan sistem monitoring energi PLTS hanya bisa diakses dari area pembangkit saja. Oleh sebab itu penelitian ini mencoba membuat sistem monitoring realtime melalui Internet of Things (IoT). Penelitian R&D ini melibatkan beberapa komponen antara lain mikrokontroller Arduino uno, ESP8266, Sensor tegangan DC, Sensor arus, Sensor PZEM-004T, Sensor DHT 11 dan Relay.

Abstract:

ABSTRACTTechnological development for off-grid housing units, integrating photovoltaic solar energy and storage systems, aims to promote energy self-sufficiency in remote areas or regions with limited access to the electrical grid. This approach enables the sustainable provision of clean energy, reducing environmental impacts and enhancing housing resilience. This study adopts a descriptive and exploratory approach, focusing on a systematic literature review and analysis of case studies documented in public sources, such as scientific articles, technical reports, and publications from companie

This article made a modest impact assessment of isolated solar home systems (SHSs) installed via recently ended five-yearflagship Ghana Energy Development and Access Project (GEDAP) on the livelihoods of rural households in the Upper WestRegion. A total of 250 solar users in both private households and rural clinics in 65 rural communities across 6 districts wereinterviewed. Lessons learned in the aspects of energy services provision, financial model, local energy preference and practicalsetbacks facing installed SHSs through GEDAP are discussed. For instance, in terms of energy preference, ma

Abstract:

In remote locations such as villages, islands and hilly areas, there is a possibility of frequent power failures, voltage drops or power fluctuations due to grid-side faults. Grid-connected renewable energy systems or micro-grid systems are preferable for such remote locations to meet the local critical load requirements during grid-side failures. In renewable energy systems, solar photovoltaic (PV) power systems are accessible and hybrid PV-battery systems or energy storage systems (ESS) are more capable of providing uninterruptible power to the local critical loads during grid-side faults.

Abstract:

Technologies that fall under alternative energy generation methods are currently among the main topics discussed in many environmental and sustainability debates. Among the most commonly used generation methods, on-grid and off-grid photovoltaic systems are prominent, mainly due to the abundance of the energy source. Offgrid, or autonomous, systems rely on energy storage, which requires the use of batteries. The construction of a battery generally involves the combination of cells. In this article, a cost analysis will be carried out to economically demonstrate the viability of a simulated bat

Abstract:

Universal access to electricity is beneficial for the socio-economic development of a country and the development of smart communities. Unfortunately, the electrification of remote off-grid areas, especially in developing countries, is rather slow due to geographic and economic barriers. In the Philippines, specifically, many electrified off-grid areas are underserved, with access to electricity being limited to only a few hours a day. This is mainly due to the high dependence on diesel power plants (DPPs) for electrifying these areas. To address these problems, hybrid renewable energy systems

Abstract:

Refrigeration systems are necessary for people living in hot climates. A majority of tropical and subtropical countries uses electrical power as a source of cooling. During the seasons of high ambient temperature there is a significant cooling load due to increased level of energy consumption. Cooling systems are therefore necessary in African countries in order to keep medications and food in safe conditions. Furthermore, there is a power shortage crisis due to the high demand for cooling. TRNSYS software allows to simulate a complete solar-powered absorption cooling system. A model used in a

Abstract:

This research applies Deep Reinforcement Learning (DRL) techniques to determine the optimal sizing of PV systems and BESS for off-grid EV charging stations by comparing the performance of the PPO, A2C, and DQN algorithms. The study found that the PPO technique yielded the best results, reducing total costs and maximizing energy efficiency, thereby reducing electricity costs by 48.79%. In terms of economics, the project is investment-worthy with an NPV of 9.7 million baht, an IRR of 20.89%, a BCR of 1.804, and a payback period of 5 years.
