Maximising distributed generation capacity in deregulated markets

The capacity of distributed generation (DG) is set to increase significantly with much of the plant connecting to distribution networks. This paper briefly reviews the technical problems associated with the connection of DG plant at distribution-level and the mitigation strategies currently available. Further it examines the shortcomings of current connection practice in terms of the potential for inadvertently limiting network capability in absorbing new DG. Finally, it demonstrates the use of optimal power flow with a technique that could facilitate maximisation of renewable generation capacity in the deregulated electricity market.
