Abstract
In this study, optimal reactive power regulation in distribution networks is achieved through the use of distributed reactive power regulators that can 1) perceive their own voltage magnitude and the P/Q flows in the connected branches, 2) communicate with nearby regulators, and 3) adjust the reactive power injections into the grid to minimize system power losses and maintain the bus voltages of nearby loads. Compared with many existing distributed reactive power regulation strategies, the proposed method can estimate and maintain the bus voltage of unmeasurable load buses within the limitations. Furthermore, this method releases the hardly achieved bus voltage angle requirement, which makes it practical for real-world.
Highlights
Distributed renewable generators (DGs) are deployed worldwide in distribution networks to produce clean, inexpensive electrical power [1]
A centralized reactive power regulation strategy can overcome this barrier by solving a centralized optimal reactive power flow (OPF) problem with a central coordinator that receives all the required measurements of the grid [9]–[11]
To cope with the above problem, a distributed optimal reactive power regulation method that does not require the bus voltage phasor is proposed in this study, where DGs are able to perceive their own voltage magnitude and P/Q flows in the connected branches, communicate with nearby DG buses, and adjust the reactive power injections into the grid, while their common objective is to minimize the total power losses of the system with maintained bus voltages
Summary
Distributed renewable generators (DGs) are deployed worldwide in distribution networks to produce clean, inexpensive electrical power [1]. The distributed OPF was achieved via linear approximation in many earlier works In this case, the detailed power system model and power flow predictions are no longer needed, but measurements at all the buses in the distribution network are still required to maintain bus voltages [13], [17]. To cope with the above problem, a distributed optimal reactive power regulation method that does not require the bus voltage phasor is proposed in this study, where DGs are able to perceive their own voltage magnitude and P/Q flows in the connected branches, communicate with nearby DG buses, and adjust the reactive power injections into the grid, while their common objective is to minimize the total power losses of the system with maintained bus voltages. Under the approximation model in the following parts, the problem can be solved much more
