User Guide for PV Dynamic Model Simulation Written on PSCAD Platform

Effect of accurate modelling of converter interfaced generation on a practical bulk power system

“…3. Implementation details such as control block diagrams in PSCAD and its usage can be found in [29]. The main difference between this model and the original positive-sequence based model lies in the generator model (REGC_A) part.…”

Integrated transmission & distribution system modeling and analysis: Need & advantages

“…However, these models are recommended for use under balanced network conditions and it is assumed that the solar power input to the plant does not change over the study duration which is about 20-30 seconds. The National Renewable Energy Laboratory (NREL) has also published several reports and research papers that can be used as guidelines for developing dynamic models of three phase and single phase inverter based DGs [8], [10], [11]. An interesting observation from both [11] and [12] is that when the objective of a study is to assess the impact of solar PV based DG on power system dynamic response, an average model for solar PV inverter may suffice.…”

Protection of Renewable-dominated Microgrids: Challenges and Potential Solutions

“…The inverter can either be voltage controlled or current controlled. In a grid connected inverter, current control enables quick response to change in real and reactive power demand [24]. Thus, most PV inverters are current controlled.…”

“…We use a constant current control strategy for the inverter simulated in this report. The inverter is implemented in PSCAD and is modeled based on a NREL report [24]. The basic block diagram of the inverter with control modules is shown in Fig.…”

“…29. The output flag V dip is set to '1', whenever voltage exceeds 1.3 pu or drops below 0.7 pu[24]. During normal conditions, V dip = 0, the limit of reactive current component I qref lies in between +i max and −I max .…”
