As a consequence of the transition to distributed and renewable energysystems, some distribution system operators are increasingly concerned aboutpower quality, including steady-state voltage volatility. In this paper, westudy the control of real and reactive power injections by inverter-baseddistributed energy resources to regulate voltage magnitudes and phase anglesmeasured by sensors positioned across 3-phase unbalanced distribution grids.Our proposed controllers are agnostic to the location and type ofcommunications supporting energy resource operations. To design thecontrollers, we apply the Gershgorin Disc Theorem and determine analyticstability regions in terms of renewable energy operating parameters and gridimpedances. The stability regions yield direct relationships between renewableenergy system siting and the convergence of voltage phasors to references.Beyond defining stability regions, we compute ranges of stable operatingparameters for renewable energy systems that promote operational flexibility byincluding customer economics. By means of a case study on the IEEE 123-nodetest circuit, we observe our approach to coordinating renewable energy systemsachieves non-oscillatory voltage regulation and reduces the duration of voltageviolations by 26%.
