AI Technical Summary
New energy systems suffer from low voltage stability, insufficient reactive power support, and reduced inertia levels. Existing synchronous condensers cannot provide active inertia support and primary frequency regulation capability, and there is a lack of active and reactive power coordination control methods for energy storage synchronous condensers.
A high-inertia energy storage synchronous condenser is adopted. By acquiring the terminal voltage and grid frequency, the active and reactive power command values are calculated, and an active and reactive power coordinated control strategy is formulated. This strategy includes the inertia support mode and the active power command value generated by primary frequency regulation, as well as the reactive power calculation expression. Combined with the converter d/q axis current coordinated control, the current is ensured to not exceed the maximum limit.
It enables synchronous support for active and reactive power during grid faults, improves the dynamic performance and stability of the grid, provides inertia support and primary frequency regulation response, and meets the needs of the grid under different fault conditions.
