Abstract

The potential of a retired electric vehicle battery (REVB) is its capacity to provide backup power supply to the power system grid. This paper proposed energy storage system (ESS) based on REVB called retired battery energy storage system (retired BESS) to tackle the intermittent of renewable energy source such as wind turbine and dynamic load change. To examine the efficacy of the proposed technique, the load frequency control (LFC) of microgrid (MG) system is utilized in this study and the proposed technique is compared to conventional LFC controller, PI controllers, superconducting magnetic energy storage (SMES), and a new electric vehicle battery. The kind of retired BESS cell used in this study is Li-ion nickel manganese cobalt oxide (NMC) type with a state of charge as of 70%. The capacity of each cell for retired BESS is 38 Ah. From the simulation result, the use of retired BESS can reduce frequency oscillation, compress the settling time to reach steady state, and maintain the robustness of the MG system. A retired BESS has a minimum error performance index value compared to conventional LFC, proportional integral (PI) controller, and SMES.

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.

Abstract

Pada artikel ini, kami melaporkan kegiatan pengabdian kepada masyarakat yang dilaksanakan oleh program studi teknik elektro universitas pertamina yang dilakukkan di SMA Al Manar Azhari. Pada realitanya teknologi informasi telah maju dengan sangat cepat dan memiliki dampak yang sangat besar. Dalam dunia pendidikan Indonesia, kedua teknologi ini masih belum sepenuhnya digunakan. Dengan bantuan laboratorium virtual, proses belajar mengajar dapat dilakukan di mana saja, kapan saja, dan menjadi lebih menarik dan partisipatif. Selain itu, waktu mengajar dapat dikurangi setengahnya sementara kualitas belajar dapat ditingkatkan. Pada pelaksanaan pengabdian ini kami menawarkan metode laboratorium virtual sebagai alat bantu pembelajaran fisika yang memiliki keunggulan lebih praktis dan biaya yang diperlukkan relatif lebih rendah. Materi yang di gunakkan dalam pelatihan ini meliputi Gerak pendulum, Rangkaian listrik DC, Gerak proyektil, dan Hamburan Rutherford. Hasil kami memperlihatkan bahwa antusias dan pemahaman peserta terhadap penggunaan laboratorium virtual PhET. Selanjutnya, hasil lain yang kami peroleh dari hasil kuisioner yang diisi oleh peserta terjadi peningkatan pembelajaran fisika dari pre-test 37 menjadi 80 saat dilaksanakkan post-test.
