The load unbalance is one of inherent features of distribution systems which draws a negative sequence current from islanded synchronous generators. This leads to overheating of the stator and, in particular, the rotor core. In such a case, it is not possible to operate the generator at its associated rated power. Thus, implementing an inverter-based resource in parallel with the synchronous ge...
As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understan...
Power grids are complex, interconnected and nonlinear systems, and this will be more severe when they are subjected to high wind resources penetration. Static synchronous compensators (STATCOM) are used to improve voltage regulation and to meet grid codes in power systems, including doubly fed induction generators (DFIG) based wind farms. Despite the nonlinear nature of STATCOM, the conventiona...
This paper presents the steps of the approach to identify the linear parameters of a salient-pole synchronous machine at standstill and by frequency response tests data (SSFR). It is currently established and demonstrated that stability parameters for synchronous machines can be obtained by performing frequency response tests with the machine at standstill. The objective of this study is to use...
