Evaluating the Impact of Network Investment Deferral on Distributed Generation Expansion

Distributed generation (DG) can offer an alternative planning approach to utilities to satisfy demand growth and distribution network security, planning and management issues. However, an appropriate framework is required to foster the integration of DG within grid network planning, thus avoiding potential inefficiencies in electricity supply infrastructure. In this work, in order to capture the effects of network investment deferral on DG expansion, different regulations for distribution network operators (DNOs) ownership of DG and how they influence the optimal connection of new generation within existing networks are examined. Using a multiyear multiperiod optimal power flow, DNOs preference for the siting and sizing of DG installation are analyzed.
