With a growing need to firm intermittent renewable energy, the demand for solar-plus-storage systems is dramatically increasing. Though both alternating current (AC) and direct current (DC)-coupled installations exist, the latter offers a range of distinct advantages, including greater round-trip efficiency, reduced equipment costs, and the ability to capture energy that would otherwise be clipped by the solar inverter.
Despite their many advantages, DC-coupled solar-plus-storage systems can be difficult to manage if not equipped with the right control technology.
Leveraging its vast technical design, consulting, and financial analysis experience across more than 6,000 MW of battery storage, Fractal EMS (Fractal) — a leading energy storage and renewable energy consulting and engineering firm that offers advanced modeling software for solar-plus-storage projects — has outlined the primary control considerations that project developers need to take into account for DC-coupled solar-plus-storage systems. Following industry best practices, Fractal also identifies a solution to overcome system control challenges, helping developers deploy the most grid-responsive solar-plus-storage power plants possible.
