AI Technical Summary
Existing technologies struggle to meet the global harmonic suppression requirements of multiple nodes and phases in low-voltage distribution networks, resulting in limited harmonic mitigation effectiveness. Furthermore, they fail to effectively suppress background harmonics propagating in medium-voltage power grids, leading to uneven inverter resource utilization and equipment overload.
By constructing a first objective function with the limit of harmonic voltage at distribution network nodes as the variable and a second objective function with the inverter harmonic current as the variable, and combining the first and second constraints, the set value of harmonic current is optimized to achieve harmonic voltage suppression across the entire network and balanced utilization of inverter resources.
It achieves precise suppression of harmonic voltage across the entire grid within specified limits, optimizes inverter resource utilization, reduces harmonic mitigation costs, and improves power quality assurance and economic benefits.
