Abstract
Penelitian ini mengusulkan metode perhitungan optimasi pada microgrid dengan pembangkit yang terhubung pada grid diantaranya photovoltaic (PV), distributed generator (DG), dan battery energy storage. Microgrid dioperasikan terhubung dengan utility grid. Terdapat fungsi multi objektif pada perhitungan optimasi ini yaitu fungsi biaya pembangkitan dan umur baterai. Transaksi energi selama charge dan discharge pada baterai akan diperhatikan untuk memaksimalkan umur baterai. Dynamic direct current optimal power flow (DDCOPF) digunakan untuk menghitung optimasi pembangkitan agar biaya total pembangkitan dapat minimal dengan tetap memperhatikan batasan batasan operasi seperti kapasitas pembangkit, kapasitas saluran, ramp rate dan energi baterai serta akan melakukan pelepasan beban pada kondisi tertentu. Dengan demikian daya terbangkit dari energi terbarukan pada sistem microgrid dapat dimanfaatkan dengan maksimal. Optimasi akan dihitung dengan metode quadratic programming.

This research presents a calculation method to optimize grid-connected microgrid system with photovoltaic (PV), microturbine, diesel, and battery energy storage. A multi-objective function added in this research contains of generation cost function and battery lifetime. The energy transaction (charging and discharging condition) is minimized to maximize battery life time. Direct current optimal power flow (DCOPF) was used to determine generated power for each generator so that total generation cost is minimal, but still considering system constraints such as branch capacity, generator capacity, ramp rate, and energy of battery, and also system will perform a curtailment in certain condition. Therefore, generated power from renewable energy sources will be operated maximally. Optimization was calculated using quadratic programming
