Simple controller implementation. In grid-connected mode, current-controlled battery energy storage systems (BESS) face the issues of harmonic caused by nonlinear loads and interactive instability under weak grids.
Recently, different methods have been used for harmonic elimination in solar energy systems. Resilient Direct Unbalanced Control (RDUC) method is one of them. It is used to reduce harmonics in the integration of solar energy systems, especially in distributed generation systems (DGs).
The harmonics in an exemplary off-grid RE system are investigated by Hojabri et al. 2013 . In the simulation study, the high voltage transient and high start-up current for inductive loads have been determined. It has been revealed that for pure resistance loads, the total harmonic distortion of current and voltage are seriously high.
In addition, it has been proven that devices working with microwave logic, devices with switched power supply and devices such as drill with universal motor and sparking on commutator cause high current harmonics in off-grid systems.
These structures other than the fundamental wave in power systems are called 'harmonic'. Due to harmonics, magnitudes such as current and voltage come out of sinus form and become quite complex.
