posted on 2015-06-04, 11:05 authored by Francisco Gonzalez-LongattFrancisco Gonzalez-LongattOne of the challenges in future energy systems is the
massive use of high power converters that decouple new energy
sources from the AC power grid, disabling natural frequency
response. This situation decreases the total system inertia
affecting the ability of power system to overcome system
frequency's disturbances. It has been established by the wind
power industry a controller to enable inertial response on wind
turbines generators (WTG) enabling the frequency response:
Artificial, Emulated, Simulated, or Synthetic Inertia. However,
there is a clear lack of knowledge about activation scheme used
for these controllers and how they work in practical manner.
This paper proposes two activation schemes for synthetic inertia
controller on WTG based on full rated power converters (FRC):
(i) under-frequency trigger and (ii) maximum-frequency
gradient trigger. Simulations considering a test system are used
for evaluation of the proposed activation schemes. The main
contribution of this paper is the definition of two schemes to
activate the synthetic inertia controller and the simulations
results that demonstrate under-frequency trigger provides the
best dynamic response in term of system frequency response.
