Solving The Problem of Excess Energy from PV Renewable Energy Sources in AAUP

Abstract

This study addresses the challenge of surplus solar energy production at Tubas Electricity Company (TDECO), driven by a substantial increase in solar power station capacity. With this surge in production, the possibility of excess electrical energy entering the grid becomes a concern, potentially leading to penalties or disconnection of electricity supply. To tackle this issue, the research employs ETAP software to conduct a comprehensive electrical network simulation in Tubas City. This simulation ensures result accuracy and evaluates the impact of new PV systems in 2023. During the project, an innovative approach was explored, involving the modification of load curves. A 5.9% reduction in the tariff for PV solar energy during peak hours incentivized customers to shift their energy consumption. This strategic loadshifting initiative aimed to align peak demand with peak generation times. Additionally, the study explores the feasibility of deploying battery storage systems to absorb excess energy. The analysis indicates that 664 batteries, each with a capacity of 200 Ah, along with 130 charge controllers rated at 250 volts and 120 amperes, would be required for this purpose. Throughout the project, a critical emphasis was placed on identifying solutions that combine cost-effectiveness with high efficiency. The findings demonstrate that both load shifting and battery storage are viable options to address the excess solar energy issue. However, the study ultimately concludes that load shifting presents a more economical and environmentally friendly choice compared to battery storage. Moreover, the ETAP simulation closely aligns with real-time data, reaffirming the applicability of these solutions in practical scenarios.
