New grid forming strategy for solar batteries

A group of scientists from a major Chinese grid operator have proposed to use an enhanced version of the particle swarm optimization algorithm to adjust inertia and damping coefficients in batteries linked to PV systems. Their approach was validated through a series of simulation and was found to enhance transient performance.
