Microgrid Solar Systems Are More Than Backup Power: Unlike traditional backup generators, solar microgrids can operate indefinitely during outages and provide continuous economic benefits through reduced electricity bills, demand charge reductions, and potential revenue.
Therefore, this chapter aims to bring an overview on harmonics origins, harmonics' standards, and harmonic mitigation methods used in smart microgrids.
They are defined in IEC 61724-1:2021 and are used by asset owners, operators, and independent engineers to detect underperformance, benchmark plants, and fulfill contractual obligations. Two primary indicators are in common use: Performance ratio (PR) and Energy performance index.
