Abstract

Sebuah sistem pembangkit listrik off-grid dibuat untuk mengatasi permasalahan pasokan listrik di Pulau Bawean. Namun, pembangkit listrik yang ada masih menggunakan PLTMG dan PLTD. Dalam “Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) PT PLN 2021-2030” akan ada penambahan PLTS di Pulau Bawean pada tahun 2024. Tujuan dari optimasi pembebanan dan penetrasi renewable energy adalah untuk mengetahui pengaruh penambahan PLTS dari segi biaya pengoperasian dan mencapai sistem pembangkitan listrik yang optimal, ekonimis, serta ramah lingkungan. Dalam permasalahan ini, perlu dilakukan optimasi pembebanan menggunakan Dynamic Economic Dispatch dengan metode Lagrange Multiplier yang kemudian dibandingkan dengan metode Particle Swarm Optimization. Optimasi metode Lagrange Multiplier tanpa PLTS memperoleh total biaya sebesar Rp 382.837.510,00. Dengan penambahan PLTS, biaya pembangkitan berubah menjadi Rp 378,450,310.00. Sehingga dapat mengurangi biaya pembangkitan sebesar Rp 4.387.200,00, atau sebesar 1,15%. Optimasi metode Particle Swarm Optimization tanpa PLTS memperoleh total biaya pembangkitan sebesar Rp 380,811,080.00. Dengan penambahan PLTS, biaya pembangkitan berubah menjadi Rp 375.826.830,00. Sehingga dapat mengurangi biaya pembangkitan sebesar Rp 4.984.250,00 atau sebesar 1,31%. Dari simulasi diketahui bahwa optimasi metode Lagrange Multiplier dapat mengoptimasi pembebanan pembangkit, tetapi tidak sebaik optimasi metode Particle Swarm Optimization.

An off-grid power generation system was created to overcome electricity supply problems on Bawean Island. However, existing power plants still use PLTMG and PLTD. In PT PLN's "Electricity Supply Business Plan (RUPTL) 2021-2030" there will be additional PLTS on Bawean Island in 2024. The aim of optimizing the loading and penetration of renewable energy is to determine the effect of adding PLTS in terms of operating costs and achieving an electricity generation system. optimal, economical and environmentally friendly. In this problem, it is necessary to optimize loading using Dynamic Economic Dispatch with the Lagrange Multiplier method which is then compared with the Particle Swarm Optimization method. Optimizing the Lagrange Multiplier method without PLTS obtained a total cost of IDR 382,837,510.00. With the addition of PLTS, the generation cost changes to IDR 378,450,310.00. So it can reduce generation costs by IDR 4,387,200.00, or 1.15%. Optimizing the Particle Swarm Optimization method without PLTS obtains a total generation cost of IDR 380,811,080.00. With the addition of PLTS, the generation cost changes to IDR 375,826,830.00. So it can reduce generation costs by IDR 4,984,250.00 or 1.31%. From the simulation it is known that the Lagrange Multiplier optimization method can optimize generator loading, but not as well as the Particle Swarm Optimization method.
