Section 4.3 Power Quality
4.3.1 Limitation of dc injection 4.3.2 Limitation of voltage fluctuations
induced by the DER 4.3.2.1 Rapid voltage changes4.3.4 Avoidance of temporary overvoltage The DER shall not cause the RMS Line-Ground voltage on any portion of the
Area EPS that is designed to operate effectively grounded, as defined by IEEE C62.92.1, to exceed 130% of its nominal line-ground RMS voltage. The DER shall not cause the L-L RMS voltage to exceed 130% of its nominal
L-L RMS voltage at any location on the Area EPS distribution system. The RMS voltage measurements of this sub-clause shall be based on one
fundamental frequency period. 4.3.5 Avoidance of transient overvoltage
– . – 4.3.2.2 Flicker…..IEC 61000-3-7.
4.3.3 Limitation of Harmonics 4.3.4 Avoidance of temporary overvoltage 4.3.5 Avoidance of transient overvoltage

Conclusions
IEEE Std. 1547rev is an opportunity to harmonize advanced DER requirements to maintain bulk system reliability in the long-term. A technology-agnostic, performance-based requirements
approach in IEEE Std. 1547rev would lead technological development and innovation of DER performance while giving sufficient flexibility to State Regulators et al. to account for regional system characteristics and societal benefits.
Success in balloting depends on stakeholder involvement! Get involved…!
