Introduction
As renewable energy continues to increase its share in power systems, energy storage has become increasingly crucial. Among various storage technologies, molten salt energy storage is emerging as a significant direction in the energy storage field due to its advantages in safety, cost-effectiveness, and longevity. This paper analyzes the impact of molten salt energy storage development on transformer demand.
Basic Architecture of Molten Salt Energy Storage Systems
A molten salt energy storage system primarily consists of four major components: a thermal storage unit, a heat exchange system, a steam generation unit, and an electrical system. The electrical system, being the core of the entire storage facility, requires multiple high-capacity transformers to meet energy conversion and grid connection requirements.
