To achieve ultra-high penetrations of converter-based resources, wind and photovoltaic power plants will be required to blackstart bulk power systems and withstand severe restoration transients. If these resources are not able to restore a power system, their incorporation into electric grids could be limited by blackstart capability.
To tackle this grand challenge, this talk introduces established advances to grid-forming technology for Type 3 and 4 wind turbines as well as photovoltaic power plants. These advances have been achieved by engineering two-axis anti-windup proportional-integral regulators that can bound abstract control signals within a circle. The features of this class of regulators are: they are elegant as well as relatively simple to implement and understand. More importantly, they can enable converter-based resources to:
(i) successfully re-energize transmission lines and cold start motor loads;
(ii) sustain the energization of unbalanced loads and nonlinear loads;
(iii) reliably ride through symmetrical and asymmetrical faults;
(iv) maintain synchronism among converter-based resources within power plants during small and large transients; and
(v) survive low-wind-speed and low-solar-irradiance scenarios to prevent a second blackout.
These advances will be demonstrated using simulations in the electromagnetic-transient and positive-sequence domains.
