CIM for power distribution reform program in India

Common Information Model (CIM) has been identified as the information exchange platform for Distribution Management. Distribution utilities in India perform multiple functions of varied nature to meet equivalently myriad challenges, in many ways unique to them. This paper discusses two of them, namely, load shedding & restoration and power purchase with scheduling. Significance of load shedding & restoration activity is apparent since India is a power deficient state. Power purchase with scheduling activity gains prominence since it involves all the three modes of fixing rate of energy namely pre-fixed, negotiable and price discovery in market. Modeling of these two use cases of Indian distribution system in CIM is presented in this paper. The essential extensions required can be derived from IEC 61970, IEC 61968 and IEC 62325. The new extensions are described. These models can be used as guideline for building CIM based software applications for them.
