چکیده
With the intensive integration of photovoltaic (PV) sources into low-voltage distribution networks (LVDN), nodal voltage limit violations and fluctuation problem cause concerns on safety operation a power system. The intermittent, stochastic, fluctuating characteristics PV output leads to frequent fast voltages. To address violation problem, this paper proposes distributed regulation method based reactive on-load tap changer transformers (OLTC). Using local Q/V (Volt/Var) feedback controller derived from grid sensitivity matrix, magnitude information is adopted adjust systems. Moreover, in order share burden among systems, weighted sharing algorithm designed achieve according rated power. Theoretical analysis provided show convergence proposed algorithm. Additionally, coordination strategy for systems OLTC reduce outputs Five simulation case studies are effectiveness strategy, where proportional can be achieved simultaneously.

Voltage Regulation of Distribution Networks through Reactive Power Control
Until recent years, the connection of dispersed Independent Power Producers to electrical networks has not been a problem for utilities, due to the fact that installed power represented a small amount of the total power connected to the system. But in the last few years this scenario is changing and especially wind energy has turn out to be one of the most important and promising sources of ren...
متن کاملInnovative Voltage Regulation Method for Distribution Networks with Distributed Generation
The presence of a significant distributed generation (DG) capacity in distribution networks would result in some conflicts with present system operation criteria, mainly because, unlike the meshed transmission system, the distribution system is usually designed as a “passive” radial system, which is conceived with neither generators operating in parallel nor power flow control. The present pape...
