Reduction of OLTC Operating in Electrical Distribution Network with Distributed Generation Source
Keywords:
electrical distribution network, source of distributed generation, synchronous compensator, OLTC, voltage controlAbstract
The variable nature of the sources of distributed generation leads to an increase in voltage fluctuations in the electrical network, which leads to an increase in the number of triggers of the OLTC system, and, as a consequence, to shorten its lifetime. In the given work the system of the coordinated control is developed by various types of voltage regulation devices with attraction of distributed generation sources having the ability to regulate the voltage in the connection node. Coordination is based on the determination of the voltage sensitivity coefficients in the nodes of the electrical network relative to the change in the reactive power of the control devices that are part of the coordinated control system. This approach allows to take into account the variable nature of sources of distributed generation, to reduce the number of actions of the voltage transformer system during voltage regulation in the distribution network, as well as to increase the output active power sources of distributed generation.
