Abstract

Seiring dengan perkembangan teknologi, terutama di bidang kelistrikan mendorong banyak produsen yang mulai menggunakan sistem pembangkit hybrid seperti PLTS. Akan tetapi, besar energi yang dihasilkan oleh PLTS mengikuti besarnya intensitas cahaya matahari, akibat nya energy yang dihasilkan oleh PLTS memiliki nilai yang fluktuatif, sehingga PLTS tidak dapat digunakan untuk mensupply energy listrik secara terus menerus. Oleh karena itu dirancanglah sebuah sitem untuk mengatur pembebanan PLTS agar pasokan listrik lebih andal dan efisien, serta dapat menambah lifetime battery. Pada tugas akhir kali ini akan dirancang sebuah Energy management storage pada sistem Hybrid PV – Grid Battery dengan mempertimbangkan data ramalan cuaca. Berdasarkan hasil analisis, EMS mampu mengatur pola pembebanan pada system sehingga suplai energi tetap terjaga selama 24 jam, SOC battery yang digunakan dibatasi hanya pada rentang 50% - 80%, sehingga battery memiliki lifetime selama 13 tahun, dengan menggunakan ramalan cuaca EMS mampu memperkirakan besar irradiansi matahari pada esok hari sehingga apabila irradiansi matahari≤121 maka EMS nantinya akan memerintahkan battery untuk melakukan pengecasan battery pada malam hari dengan menggunakan suplai daya yang dikirimkan oleh grid PLN.
================================================================================================
Along with technological developments, especially in the electricity
sector, many manufacturers have started to use hybrid generating systems
such as PLTS. However, the amount of energy produced by PLTS follows
the intensity of sunlight, as a result, the energy produced by PLTS has a
fluctuating value, so that PLTS cannot be used to supply electrical energy
continuously. Therefore, a system was designed to regulate the PLTS
loading so that the electricity supply is more reliable and efficient, and
can increase battery lifetime. In this final project, an Energy management
storage system will be designed for the Hybrid PV – Grid Battery system
by considering weather forecast data. Based on the results of the analysis,
EMS is able to adjust the pattern of loading on the system so that the
energy supply is maintained for 24 hours, the SOC battery used is limited
to only the range of 50% - 80%, so the battery has a lifetime of 13 years,
using weather forecasts EMS is able to estimate the size of the battery. the
solar irradiance tomorrow so that if the solar irradiance is ≤121 then EMS
will later instruct the battery to charge the battery at night using the power
supply sent by the PLN grid.
