SMART INVERTERS FOR DISTRIBUTED GENERATORS (Room C148)

Different countries are setting up ambitious targets of PV solar based Distributed Generators (DGs) installations. However, the integration of PV based DGs has led to several challenges, mitigation of which typically requires expensive compensating and protection equipment, as well as complex network management strategies.

DG inverters primarily produce real power at unity power factor. However, power electronics has now made it possible for inverters to perform multiple functions for grid support, in addition to real power generation. Such inverters are termed Smart Inverters as they are capable of effectively minimizing several grid integration challenges of DGs without additional equipment. Recognizing the significant potential of smart inverter technology, utilities across the globe are actively considering implementation of smart inverters.

The technology of smart inverters is new and rapidly evolving and has outpaced the technical regulations and standards which are needed to allow its implementation. Different PV interconnection and testing standards around the world are being revised to allow the different features of smart inverters to be implemented. US DOE, EPRI, NREL are testing and demonstrating the smart inverter technologies on several pilot projects.

This tutorial will present a comprehensive and structured knowledge on the need, functions, operation and protection, integration and testing standards, system studies of benefits, demonstration projects and actual installations of this new technology. This tutorial will be very helpful for academics, utilities, practising engineers, consultants, system operators and planners, DG developers and inverter manufacturers for understanding the various facets of this technology and to fully exploit its vast capabilities in their T&D grids.
