Abstract

Perkembangan teknologi memungkinkan digunakannya energy storage sebagai solusi masalah manejemen energi karena integrasi energi terbarukan. Kemampuan energy storage untuk menyimpan daya (charging) dan menyalurkan daya (discharging) dapat dimanfaatkan untuk mengatasi sifat energi terbarukan yang intermittent. Pada penelitian ini, energy storage diintegrasikan ke dalam sistem microgrid dan dimodelkan sebagai generator dan beban. Selanjutnya, integrasi energy storage untuk mendapatkan keuntungan dipelajari lebih jauh dengan mempertimbangkan harga charging dan discharging. Perhitungan Dynamic DC Optimal Power Flow (DDCOPF) digunakan untuk mengoptimasi sistem dengan energy storage pada beban dinamis. Metode Mixed-Integer Quadratic Programming diaplikasikan menggunakan software MATLAB untuk menyelesaikan perhitungan DDCOPF. Simulasi dilakukan pada IEEE 30 Bus Test System yang telah dimodifikasi dengan pembangkit berjenis microgrid. Hasil dari perhitungan ini adalah daya keluaran generator dan energy storage dengan biaya pembangkitan minimum pada tiap level beban serta efek dari perbedaan harga charging dan discharging terhadap hal tersebut. Dari hasil simulasi dan analisis, perbedaan harga charging dan discharging menghasilkan biaya pembangkitan yang lebih tinggi 0.79% dibandingkan dengan penerapan harga sama. Selain itu, perbedaan harga tersebut meminimalisir penggunaan enegy storage. ============================================================================================== The development of technology makes it possible for energy storage utilization as solution for energy management problem due to renewable integration. The ability of energy storage to store and supply power can be used to solve intermittency problem of renewable energy. In this research, energy storage is integrated in a microgrid system and modelled as generator as well as load. Furthermore, integration of energy storage is researched deeper considering charging and discharging cost. Dynamic DC Optimal Power Flow (DDCOPF) calculation is used to optimize system with energy storage in fluctuated load. Mixed-Integer Quadratic Programming method is applied using MATLAB software to solve DDCOPF calculation. Simulation is done on IEEE 30 Bus Test System modified with microgrid as the power source. The output of this calculation are generation power and energy storage power in each period with minimum generation cost and the effect of different charging and discharging cost towards it. From the simulation and analysis, the different charging and discharging cost produce 0.79% higher in total generation cost compared to the same cost. In addition, the different charging and discharging cost also minimizes the energy storage usage in the system.
