Title
Distributed Voltage Regulation In Distribution Power Grids: Utilizing The Photovoltaics Inverters
Abstract
Millions of newly installed photovoltaic (PV) panels are disrupting the conventional distribution power grid operation. The lack of efficient coordination schemes between the PV panels results in voltage stability issues. In this paper, we exploit the reactive power control potential in the inverters of the PV panels for voltage regulation. There are considerable obstacles to design a coordination scheme that does not rely on a central entity with theoretical performance guarantee. In particular, the power flow equations define a highly non-convex constraint set. To tackle this challenge, we first examine the structure of the problem for a simplified linear network model, which allows for the design of a distributed control scheme. Then, we devise an analytical framework to show that our proposed distributed scheme will converge to a local minimum geometrically in the non-convex branch flow model. We further characterize the systematic error during the convergence. Finally, we use simulations to assess the performance of our proposed scheme.
