چکیده

The large-scale deployment of the Smart Grid willsupport the evolution of conventional electrical power systemstoward active, flexible and automatic troubleshooter energynetworks composed of renewable energy resources. With theincreasing penetration of renewable energies as distributedgeneration (DG) in smart grid scheme, technical problems arisein both distribution and transmission system level. Theundesirable voltage is the main problem for connection of DGsin distribution systems, while excessive reactive power demandfrom transmission system is the major concern for TransmissionSystem Operators (TSO). This paper presents a new subframeworkin the reactive power management to optimalcontrol of voltage in the suitable range by decreasing thevoltage deviation and obtain high voltage stability margin,simultaneously. In this work, the required voltage profile, by setof controllable variables in power system such as tap oftransformers, value of capacitors is investigated. Todetermination the value of elements in the mentioned subframework,the Particle Swarm Optimization (PSO) method isemployed to rapidly obtain the optimum parameters due toimprovement of voltage profile. Finally, the proposed method isimplemented on the standard IEEE- 24 bus and IEEE-16 busdistribution system the results are compared to each other.
