Abstract
Penjadwalan daya charge dan discharge energy storage pada sistem penyimpanan energi hibrida secara optimal dan ekonomis atau (economic dispatch) sangat diperlukan. Tujuannya adalah untuk meniminalkan biaya daya energy storage namun kebutuhan beban dan batasan-batasan yang ditetapkan dapat terpenuhi. Dalam penelitian ini, sistem penyimpanan energi hibrida yang terdiri dari baterai dan superkapasitor dirancang pada pembangkit listrik tenaga surya (PLTS) off-grid. Metodologi penelitian yang digunakan untuk optimasi economic dispatch energy storage adalah metode mixed integer linear programming. Penelitian dilakukan dengan simulasi menggunakan software MATLAB R2022b. Hasil penelitian menunjukkan penjadwalan daya charge dan discharge dari baterai dan superkapasitor yang optimal dan memenuhi batasan-batasan yang telah ditetapkan. Hasil juga menunjukkan DOD baterai sebesar 38,764% kapasitas energi baterai dan DOD superkapasitor sebesar 80% kapasitas energi superkapasitor. Selain itu, biaya daya baterai sebesar $0,236, biaya daya superkapasitor sebesar $0,053183, serta biaya daya sistem penyimpanan energi hibrida sebesar $0,289183 dalam 24 jam.

Optimal and economic scheduling of charge and discharge power for hybrid energy storage systems is crucial, known as economic dispatch. The objective is to minimize the cost of energy storage while fulfilling the load requirements and imposed constraints. In this study, a hybrid energy storage system consisting of batteries and supercapacitors is designed for an off-grid solar power plant (PV off-grid). The research methodology employed for optimizing the economic dispatch of energy storage is the mixed-integer linear programming method. The research is conducted through simulations using MATLAB R2022b software. The research findings demonstrate the optimal scheduling of charge and discharge power for batteries and supercapacitors, satisfying the predefined constraints. The results also indicate a battery Depth of Discharge (DOD) of 38.764% of the battery's energy capacity and a supercapacitor DOD of 80% of the supercapacitor's energy capacity. Furthermore, the cost of battery power is $0.236, the cost of supercapacitor power is $0.053183, and the cost of the hybrid energy storage system's power is $0.289183 over a 24-hour period.
