Design of photovoltaic system for public school building

Abstract

The increase in energy needs to support sustainable development will trigger a large additional power supply. Unfortunately, a current energy source is mostly produced by fossil fuels. This condition can affect the increase of global warming and climate change. Nowadays, many countries including Indonesia are aware of the effect of the use of fossil fuels on environmental devastation. Therefore, the use of clean energy gets more attention from many countries since its energy source is unlimited and harvested from nature. One of the clean energy sources that are widely utilized over the world is photovoltaic (PV). PV is an appropriate clean energy technology to be utilized in Indonesia since this country lies on the equator line and gets solar irradiance over the year. This paper proposed the design of PV systems for a public-school building. These PV schemes proposed in this study are classified into off-grid, on-grid, and hybrid PV systems. From the simulation results, it is shown that the hybrid PV system with energy supplied by PT. PLN (State Electricity Company) results in the highest saving annual cost and provides an environmentally friendly energy source for public-school buildings.

Impact of cell temperature on the performance of a rooftop photovoltaic system of 2.56 kWp at Universitas Pamulang

“…From Figure 8, solar irradiation is measured with the lowest value of 509 W/m 2 at 11:00 AM this indicates cloudy weather conditions, while the highest value of 944 W/m 2 at 13:00 PM with an average solar irradiation of 702.7 W/m 2 . This indicates sunny weather with ideal solar radiation values close to the STC value at 1000 W/m 2 [29], [30]. Same as solar radiation measurements, cell temperature measurements were carried out for each solar panel using the solar survey 200R product from Seaward as shown in Figure 9.…”

Enhanced low voltage ride-through control of multilevel flying capacitor inverter based wind generation

“…The substantial rise in atmospheric carbon dioxide levels is strongly linked to the industrial revolution and the increasing energy demand [1]. With the energy sector accounting for approximately two-thirds of emissions, the integration of renewable energies into electricity grid infrastructure will be pivotal in reducing carbon emissions in the near future [2], [3]. Wind power, both onshore and offshore, has already taken a prominent role in our electricity system [4], [5].…”

Stability analysis of smart grid management system on campus building

“…One way to avoid the cessation of electricity supply from PLN is to rely on electrical energy sources from solar panels [7]. Through the feasibility analysis of using electrical energy sources from solar panels, a smart energy management is needed [8], [9].…”
