Fair coordination of distributed energy resources with Volt-Var control and PV curtailment

This paper presents a novel distributed optimal power flow (DOPF) method for fair energy resource (DER) coordination in the context of mandated rooftop PV inverter control modes. In practice, reactive is increasingly required by grid connection codes, which often unfairly curtail generation prosumers towards end low-voltage feeders. Similarly, optimization-based DER methods that aim solely technically-efficient do not consider distribution curtailment across customers. To address these concerns, we develop tractable multi-objective DOPF (i) curtails fairly prosumers, and (ii) incorporates standard piecewise-linear volt-var function without using integer variables. Three equity principles representing different interpretations fairness are implemented our method; namely, egalitarian, proportional uniform dynamic redistribution. The performance approach demonstrated on feeders sizes (5, 10, 25, 50 100 prosumers) two network topologies: line topology lateral spurs tree with spurs. Each considers three levels penetration, giving 30 test systems total. results demonstrate effectiveness proposed coordination: equitably among computational burden par conventional approaches. Moreover, result patterns curtailment, regulator may choose between.
