ABSTRACT

The modern power distribution system is integrated with more renewable energy resources and flexible loads which makes the network more active. Proper co-ordination and control of the distribution grid assets are required to maintain system stability and reliability.   For real time control, the state of the system is required which can be estimated from the data obtained from smart meters installed at critical locations. The heterogeneous communication technologies can be utilized for sharing of information. The distribution system operator (DSO) has to operate the system in co-ordination with transmission system operator (TSO) through proper interface.

In this project, multi-stage control architecture, adaptive protection and grid reconfiguration scheme in active distribution grids will be proposed.  The project work will involve analysis and development of hierarchical and distributed control and coordination schemes of grids assets and demand-side participation. Provisions for demand side management, Volt/Var optimization and ancillary services will be made amid large amount of renewable energy generation and flexible loads. The control architecture will be supported by real time state estimation of the distribution grid. Assessment of such advanced distribution grid management system on the TSO-DSO interface and smart grid flexibility markets will be investigated and validated.
