Photovoltaic-Based Solar Power Plant as a Renewable Energy Source in the Gunung Ledek Conservation Area at UNNES

Objective: This work proposed a comprehensive techno-economic analysis and optimization of renewable energy systems focusing on PV technology within UNNES conservation park area. Theoretical Framework: The integration of renewable energy sources (RES) in campus settings contributes to reducing carbon footprints and serves as a practical educational medium. In this case, the Hybrid Optimization Model for Electric Renewables (HOMER) software can be utilized to research the optimal configurations. Method: This work utilizes a load profile based on the electricity demands of commercial and industrial networks within the HOMER software. In addition, the solar daily radiation with clearness index and temperature for the selected location was derived from the Solar Global Horizontal Irradiance (GHI) profiles. Results and Discussion: The most optimized system configuration consists of a 1,376 kW Flat-plate PV, 822 kW system converter, and grid utility to handle load profile characteristics for electricity consumption with an entire daily usage of 24,165.44 kWh and peak demands reaching 1,853.66 kW. The net present cost (NPC) is calculated to be $13,213,250, with the $0.0891/kWh cost of energy (CoE). In addition, the renewable energy fraction is achieved by 21.4-23.9% and generates 2,184,625 kWh annually from solar PV string. Research Implications: This research provides insights into how educational institutions can contribute to the energy transition by integrating RES. Originality/Value: The study was conducted at the UNNES conservation park area and has a prospect to realize because this institution formally declared itself a Conservation University, which involves safeguarding, protecting, preserving, and wisely utilizing natural resources.
