IEEE 519 is a recommended practice that sets limits for harmonic distortion at the Point of Common Coupling (PCC), which is the point where a user's electrical system connects to the utility grid. It places responsibility on both the utility and the customer to maintain power quality. . This study aims to investigate the causes of harmonics in PV Inverters, effects of harmonics, mitigation techniques & recent integration requirements for harmonics. PV inverters convert DC to AC power using pulse width modulation. . Solar inverters use a technique called Pulse Width Modulation (PWM) to create an AC waveform from a DC source. While incredibly efficient, this rapid switching process inherently generates harmonic currents. However, all PWM methods. . Harmonics are unwanted frequency components in the electrical signal that deviate from the fundamental frequency (usually 50 or 60 Hz, depending on the region).

Storage systems may also be used to import or export electricity outside of Mexico, but this requires an import or export authorization from SENER. Storage permits will specify the type of services that can be provided by the permit holder.
Energy storage systems operating independently from power plants or load centers and with capacities of more than 0.7 MW require a storage permit from CNE, while battery storage systems that are co-located with power plants can share the generation permit and are not required to obtain a separate permit.
Mexico is making room for several types of private projects. Private parties may develop power plants whose output is sold into the wholesale electricity market so long as such power plants do not conflict with the binding planning criteria issued by the Mexican government.
Mexico released new guidelines earlier this month for private power projects. It intends to fast track projects that are included in annual development plans. The first electric sector development plan was issued on October 17. The guidelines are in regulations issued to implement the 2025 Electric Sector Law, or LESE.
