Description

The power electronic based Grid Side Converter (GSC) is the key technology for interconnecting RES. In order to obtain accurate simulation results, it is important to have a detailed-realistic modelling of GSCs. This requires a very small solver step (i.e., solver period near 1 μs) due to the high-frequency switching operation of these converters. Such a small solver period imposes computational constraints, especially when there is a need to investigate the dynamic power system operation with several installed RESs. This paper proposes a simplified but still very accurate modelling solution for the GSC of RES for performing accurate and dynamic simulations with a significantly larger solver step. A case study is also demonstrated, where the proposed model of the GSC is utilized to investigate the interaction between several distributed RESs (with advanced controllers) and the power grid.
