Abstract

Photovoltaic (PV) is an environmentally friendly renewable energy source. Photovoltaic when connected directly to the load, the power delivered to the load is not optimal. Therefore it is important to get maximum power from the PV system to increase efficiency. This study presents an MPPT system using the Incremental Conductance (IC) algorithm to analyze PV systems installed in parallel and installed in series using 3 PVs. This IC algorithm works by monitoring the current gradient to determine the direction of voltage change and providing a change in derivative voltage so that it can determine the speed of delivery. From the results of the study, the average power using 3 PVs installed in series was 95.4% and using 3 PVs installed in parallel was 88.44%. The algorithm (IC) has a faster response in tracking the maximum power point when installed in parallel even though its efficiency is lower. However, current variations when there are changes in solar radiation tend to be constant as long as the temperature conditions are close to stable.

Abstract

Photovoltaic (PV) is an environmentally friendly renewable energy source. When Photovoltaics are connected directly to a load, the power delivered to the load is not optimal power. Therefore, it is important to get maximum power from the PV system thereby increasing efficiency. Various maximum power point tracking (MPPT) techniques of PV systems are proposed, such as Perturb and Observe (P&O) algorithm. MPPT techniques are usually limited to uniform weather conditions. This research presents an MPPT system with a series of DC-DC Boost converters under conditions of changes in solar irradiation, each change is assumed to last 5 hours and a temperature of around 250C, while the amount of solar irradiation is 300 W/m2, 500 W/m2, 700 W/m2 and 1000 W/m2. From the results of research carried out with the help of MATLAB simulations, it was found that the average efficiency was 95.6% and obtained low oscillation MPP tracking as well as fast and dynamic response during stable weather conditions.

Abstract

In order to improve energy conservation efforts and comfort in building structures, all building managers such as professional associations, consultants, contractors, suppliers can apply the concepts of lighting system design procedures in building structures that can be utilized by planners as required by SNI 6197:2020. In this study, technical calculations were carried out using dialux evo software to obtain lighting intensity based on the function of the residential room. From the results of the research that has been carried out, the minimum average lighting level of the lighting intensity of each room function in natural lighting during the day, there are 2 rooms that meet the requirements, namely the bedroom and bathroom (KM1, for this purpose artificial lighting is carried out using lamps, at night the minimum average lighting level on the first floor gets a large lighting intensity of the room that meets the requirements based on SNI 6197:2020 which is required for each room function. To save energy, the bedroom and bathroom (KM1) switches are in the off position during the day while at night the switches for each room are in the on position.

Abstract

The automotive sector is very important to achieve net zero global emissions to limit global warming because 65% to 80% of the emissions produced come from exhaust and indirect emissions come from fuel. In 2050, the volume of oil production is expected to fall by 55% and gas by 70% and coal will no longer be produced. For this reason, regional governments, especially Jambi province, can be pioneers in preparing to use electric vehicles, starting with the use of official cars in every government agency. Muaro Jambi Regency (Sengeti) is 30.4 km from Jambi City, where the average government employee lives in Jambi City and uses fossil fuel official cars every day. This is of course a long-term global energy security problem. In this research, data analysis was carried out regarding solar radiation and energy production of Photovoltaic (PV) systems using the Photovoltaic Geographical Information System (PVGIS) web application located at the Muaro Jambi DPRD office where the data was used as charging infrastructure for 1 electric car in one trip. . From the research results, there is potential for Photovoltaic (PV) system energy as infrastructure for charging electric cars and allows for 2 units of electric cars with the same specifications, because there is an average energy per day that is not captured at 5512.2 Wh.
