Abstract

Electrical energy is a necessity for individuals, households, and industries. Along with the increase in population and technological development, the need for electrical energy consumption increases. PLN is not always able to provide electricity continuously, so a backup power plant is needed to ensure continuity of electricity supply. To overcome this problem and reduce the use of fossil energy, alternative power plants based on new renewable energy (EBT) were developed. One example is the Solar Power Plant (PLTS) which utilizes abundant solar energy and does not produce harmful emissions. Optimization of this combination can be done with an Automatic Transfer Switch (ATS) system that automatically moves the connection between power sources. In the Automatic Transfer Switch system that can be programmed to switch between resources from PLTS and PLN timer to set the ATS operating time, in this ATS system the required components are timer and LDR. The timer will be used to set the ATS operating time, specifically to limit the use of solar panels to a certain time range. The LDR sensor is used to change the battery charging.  

Review

This paper addresses a highly pertinent issue in modern energy systems: the escalating demand for electrical energy coupled with the need for reliable supply and sustainable sources. The abstract effectively highlights the limitations of conventional grid supply (PLN) and the environmental imperative to integrate new renewable energy solutions. The proposed solution, an Automatic Transfer Switch (ATS) system for battery charging using a combination of solar panels (PLTS) and grid electricity, positions the work at the intersection of energy security and sustainability, aiming to ensure continuous power while reducing reliance on fossil fuels. The core of the presented work revolves around an ATS system designed to optimize power sourcing from PLTS and PLN for battery charging. The abstract specifies that this system is programmable and utilizes a timer and an LDR sensor. The timer's role is described as setting the ATS operating time and limiting solar panel usage to a certain time range, implying a time-based control strategy, which could be beneficial for load shifting or grid interaction. However, the abstract's description of the LDR sensor's function, "to change the battery charging," remains somewhat ambiguous. While LDRs are typically used for light sensing (e.g., to detect day/night or solar irradiance), a direct mechanism by which it "changes" battery charging needs further technical elaboration to understand its specific contribution to the ATS logic or battery management beyond simply detecting ambient light for solar panel activation. Overall, the concept of an intelligent ATS for hybrid solar-grid battery charging is sound and holds significant promise for improving energy resilience in households and industries, particularly in regions experiencing intermittent grid supply. The paper's strength lies in its practical application of renewable energy integration with a focus on automation. To fully appreciate the novelty and robustness of the proposed system, the full manuscript would ideally detail the specific switching criteria (e.g., battery state of charge, grid availability, time), the control algorithm governing the timer and LDR interactions, and the precise mechanism by which the LDR influences battery charging. Clarification on these aspects would significantly enhance the understanding of the system's operational logic and its potential impact on overall energy efficiency and battery longevity.
