A New Reliability and Security Oriented Technique for Optimal DG Placement in a Practical Distribution Network

A Model Predictive Control Volt/VAr Management System for the Froan network

“…As observed by [21], it may be beneficial to dispatch ESS and RES assets at the same bus nodes, due to high R /X ratio's, as is the case for the Froan network. Locations of these assets (busses [1,55,22]) are chosen in-line with earlier work of [18] which stipulates locations for energy injection based on network loss sensitivities and voltage stability factors. The VVM MPC strategy (8) has a sampling rate of h = 1 [s].…”

“…Dispatched diesel DG assets, d ∈ D, may have transient response times being substantially lower than that associated with typical ESS assets (i.e., switching of ultra capacitor banks). To such an extent, to model slow transient behaviour of DG assets, and their energy contributions towards (2), we consider the following generic discrete first-order dynamics for each dispatched DG asset: Here we assume that the nominal active/reactive power of the respective DG asset, (P D,d nom , Q D,d nom ), are determined during sizing and planning phase [18].…”

“…In this instance, it is desirable to determine the placement of DG assets with appropriate sizing within a deterministic network setting which promotes distribution network loss minimization and voltage stability improvements. The sizing (i.e., values for (P D,d nom , Q D,d nom ) in (4c)) and placement (d ∈ D) has previously been determined for the Froan case [18]. Here, we consider the voltage profiles and phase angles, ( V i , δi ) ∀i ∈ M (as evaluated for the ACOPF solution during planning and sizing in [18]) as desirable reference points.…”

To follow are brief formulations to the weighted multiple objectives optimized in the context of dynamic power quality management in aim of promoting increased network resilience.…”
