Energi listrik adalah hasil dari metode konversi, seperti dari konversi energi panas, konversi energi kinetik, konversi energi angin, dll, dan telah memungkinkan untuk mengkonversi energi matahari menjadi energi listrik dengan bantuan modul fotovoltaik. Tapi karena matahari tidak bersinar sepanjang waktu atau dengan intensitas yang sama, perlu kita untuk menyimpan energi listrik yang lebih untuk digunakan nanti. Untuk menyimpan energi listrik kelebihan ini, kita dapat membuat sebuah sistem yang menyimpan kelebihan energi ini dengan menyimpannya dalam Electrical Storage System (ESS). Dalam tesis ini, EES terdiri dari baterai yang dapat menyimpan kelebihan energi tetapi pada saat yang sama juga dapat menarik energi tergantung pada kebutuhan daya beban. Target dari skripsi ini adalah untuk menciptakan sebuah sistem penyimpanan energi listrik yang dapat dihubungkan dalam sebuah pembangkit listrik PV yang sudah ada. Sistem tersebut harus mencakup kontrol pengisian dan pemakaian baterai. Analisis State of Charge (SOC), tegangan operasi baterai, dan state control baterai akan ditampilkan dan dibahas. Hasil simulasi menunjukkan bahwa baterai mampu di charge dan discharge pada radiasi tertentu dengan tegangan sistem yang diperlukan. Baterai mampu memberikan 200kW saat pemakaian.

Electrical energy is the result of many conversion methods, such from heat energy conversion, kinetic energy conversion, wind energy conversion, etc., and it has been possible to convert solar energy directly to electrical energy with the help of photovoltaic modules. But since sun does not shine all the time or with equal intensity it is necessary to store any excess electrical energy produced during the day for later use. To store this excess electrical energy, we can create a system that saves the excess energy by storing it in an Electrical Storage System (ESS). In this thesis, the EES includes a battery that can store excess energy but at the same time be able to draw energy at any time of the day, depending on the load power requirement. The target of this thesis is to create an electrical storage system that can be connected in an existing PV power generation. The system should include the battery's charging and discharging control. An analysis of the battery's state of charge (SOC), battery?s operating voltage, and battery state control will be discussed. The result of the simulation shows that the battery is able to charge and discharge at a certain irradiance with the required system voltage. Battery is able to supply 200 kW when discharging.

Kendaraan Listrik saat ini tengah digencarkan oleh pemerintah Indonesia karena kelebihannya untuk tidak menghasilkan emisi karbon dioksida. Kendaraan listrik memanfaatkan baterai sebagai sumber energi utama untuk menggerakan motor dan perangkat listrik yang digunakan. Pengisian ulang perlu dilakukan oleh baterai dikarenakan energi listrik yang terkandung akan habis diserap oleh komponen-komponen listrik yang digunakan. Perangkat pengisian baterai akan menerima energi listrik dari Jaringan Listrik Distribusi dengan sistem tegangan AC tiga fasa dan mengonversikannya menjadi sistem tegangan DC. Konversi tegangan tersebut akan dilakukan oleh perangkat yang disebut sebagai rectifier. Topologi 2 – level converter akan digunakan karena kemampuannya untuk mencapai sistem dengan unity power factor dan rendahnya tingkat harmonik arus. Metode kendali berorientasi tegangan dipilih dikarenakan tingkat dinamika yang tinggi serta performa statis yang baik melalui pengendalian arus lingkaran dalam. Pemilihan nilai parameter merupakan hal yang krusial dikarenakan dapat mempengaruhi kestabilan sistem. Pemodelan, simulasi, dan analisis sistem secara matematis perlu dilakukan sehingga sistem tetap berada di rentang kestabilan sesuai dengan batasan spesifikasi yang telah diperoleh. ......The Indonesian government is currently intensifying electric vehicles because of their advantages of not producing carbon dioxide emissions. Electric vehicles utilize batteries as the primary energy source to drive motors and electrical devices used. The battery's recharging needs to be done by the battery because the electrical energy will be entirely absorbed by the electrical components used. The battery charging device will receive electrical energy from the Distribution Electric Network with a three-phase AC voltage system and convert it into a DC voltage system. The voltage conversion will be carried out by a device called a rectifier. The 2-level converter topology will be used to achieve a system with a unity power factor and low current harmonic levels. The voltage-oriented control method was chosen due to its high dynamics level and good static performance through inner circle current control. The selection of parameter values is crucial because it can affect the stability of the system. Mathematical modeling, simulation, and analysis of the system need to be carried out to remain in the stability range according to the specification limits obtained.

An active Radio-Frequency Identification (RFID) tag is a low-power device, which is often used as a tracking device, where operation of this tag will be in remote areas from an electrical power source. Therefore, this device requires an independent power source. To meet these needs, solar power may be used, which can be accessed anywhere there is sunlight. Supercapacitors (SC) are used as an energy source to support a solar power system. The advantage of supercapacitors, as an energy storage device, is their long life cycle that means more charging and discharging processes compared to a conventional battery. The design and fabrication of a solar power system for an active RFID tag with supercapacitors as the energy storage will be covered in this paper.
