The use of automation and energy efficient equipment with electronic control would greatly improve industrial production.  These new devices are more sensitive to supply voltage deviation and the characteristics of the power system that was previously ignored are now very important. Hence the benefits of distribution automation have been widely acknowledged in recent years. This paper proposes an efficient load flow solution technique extended to find optimum location for reactive power compensation and network reconfiguration for planning and day-to-day operation of distribution networks.  This is required as a part of the distribution automation system (DAS) for taking various control and operation decisions.  The method exploits the radial nature of the network and uses forward and backward propagation technique to calculate branch currents and node voltages.  The proposed method has been tested to analyze several practical distribution networks of various voltage levels and also having high R/X ratio.

Reasonable Choice

In order to reap the benefits promised by the Smart Grid, communications between the IEDs in IEC 61850 Substation Automation System (SAS) will need to be made much more secure.Traditional security solutions based on Public Key Infrastructure (PKI) are calculation intensive and introduces latency that will be difficult to meet substation environmental and electrical requirements, so they are not well suited for IEC 61850 SAS. Identity based encryption (IBE) schemes, introduced by Shamir in 1984 [5] are based on the idea to use participant’s unique identities as public key and public key directories are unnecessary. Thus, utilizing IBE in IEC 61850 SAS is a reasonable choice. This paper briefly introduces the features of IEC 61850 SAS communication security and IBE and then propose an IBE-based Self Private Key Generated (SPKG) encryption scheme to establish encryption system in IEC 61850 SAS. Advantages of this SPKG Scheme are also discussed in the paper.
