Abstract

This paper widens the knowledge about the microgeneration transient response under faulted conditions. The paper provides the following significant contributions: Firstly, a range of microgeneration transient models have been developed in PSCAD/EMTDC and tested on a typical distribution network. Two types of technologies are considered: a small diesel engine driving a three-phase synchronous machine connected within commercial premises; and a small microwind turbine interfaced directly within residential dwellings by a single-phase induction generator. Secondly, a valuable insight into the transient behavioral of this range of technologies during and after the clearing of remote faults at a medium voltage (MV) distribution system is provided, and their resilience levels are quantified. Thirdly, for reliable microgeneration operating in parallel with the distribution networks, the paper includes a discussion on some of remedial measures by which the transient stability of a large penetration of microgeneration may be improved. Also in this paper the inclusion of resistive superconducting fault current limiters into medium voltage distribution systems has been proposed as one of the practical solutions that can enhance the transient performance of large numbers of low voltage connected microgeneration. The effectiveness of fault current limiters on the grid-connected microgeneration transient stability enhancement has also been evaluated.
