Performance Analysis of Hybrid Energy Storage Systems in Abandoned Mines: Peak-Shaving and Load Balancing using Multi-Source Heat Storage

다국어 초록 (Multilingual Abstract)

This paper presents a multi-source thermal storage for peak shaving and load balancing to improve the performance of Hybrid Energy Storage (HES) systems for abandoned mines. The proposed system combines renewable energy sources, such as solar, wind, and traditional power sources, and use Information Gap Decision Theory (IGDT) to optimize scheduling under uncertainties. Furthermore, it implements a Multi-Source Thermal Storage Peak Shaving (MSTSPS) with a Load Balancing Strategy (LBS) to manage variable loads effi ciently, which signifi cantly reduces peak-to-valley load differences and scheduling costs. In the end, it presents a case study using IEEE-39 nodes to evaluate the performance of the proposed work. Results show that the proposed system reduced peak-to-valley load diff erences with substantial cost savings, highlighting the potential of abandoned mines as sustainable, cost-eff ective storage solutions for renewable energy.
