This paper considers distribution networks featuring distributed energy resources, and designs an incentive-based algorithm that allows the network operator and the end-customers to pursue given operational and economic objectives, while concurrently ensuring that voltages are within prescribed limits. This social-welfare maximization problem is challenging due to the non-convexity. We first reformulate...
Motivated by the inability of the existing local voltage control schemes to stabilize the voltages to within the acceptable ranges, we propose a new local voltage control algorithm where each bus adjusts incrementally its reactive power in response to its voltage deviation from the nominal value. We show that the dynamical system with the proposed incremental control can be seen as a distributed algorithm...
Inverter-based voltage regulation is gaining importance to alleviate emerging reliability and power-quality concerns related to distribution systems with high penetration of photovoltaic (PV) systems. This paper seeks contribution in the domain of reactive power compensation by establishing stability of local Volt/VAr controllers. In lieu of the approximate linear surrogate used in the existing work,...
Voltage regulation is critical for distribution systems, and has become a much more challenging problem with the increasing proliferation of distributed renewable energy resources that cause frequent and rapid voltage fluctuations beyond what can be handled by the traditional voltage regulation methods. In this paper, motivated by the shortcomings of two previously proposed inverter-based local volt/var...
In this paper, we consider the signal-anticipating behavior in local volt/var control in distribution systems. We define a voltage control game, and show that the signal-anticipating voltage control is the best response algorithm of the voltage control game. We further show that the voltage control game has a unique Nash equilibrium, characterize it as the optimum of a global optimization problem,...
