Distribution system optimisation with intra-day network reconfiguration and demand reduction procurement

The evolution of distribution automation technologies and the advances in distribution system optimisation studies are enabling the implementation of network configurations that are variable in time, with a limited number of configuration changes per day. The first part of this paper addresses the definition of pseudo-optimal intra-day distribution system configurations based on multi-scenario analysis handled with decision theory concepts. The resulting configurations are then used to formulate a demand response scheme for a given time period, aimed at procuring demand reductions to further decrease the distribution system losses. This scheme is driven by the calculation of the marginal loss coefficients and by the customers’ willingness to participate in the demand response action. A dedicated offer scheme to be introduced in a benefit-based mechanism for optimal demand procurement is formulated and discussed.

► Decision theory-based configuration selection for intra-day optimal reconfiguration. ► New prospect of providing demand side incentives to reduce the network losses. ► Formulation of a demand response (DR) scheme for demand reduction procurement. ► Formulation of a dedicated offer scheme for customers’ participation in the DR action. ► Benefit-based optimisation for demand reduction procurement.
