A New Restoration Process in Power Systems with Large Scale of Dispersed Generation

Abstract

This paper presents a new effective restoration procedure designed for the Electrical Power System (EPS) with large scale of dispersed generation (DG) penetration. The "deep build -together" strategy is proposed to simultaneously consider this rebuilding by transmission and distribution networks, thereby, to serve the maximum of customers in a minimum of time. The restoration problem has to be now formulated as a multilevel, multi-objective optimization problem with constraints. The proposed method is designed with consideration to the network in the coming year which requires the introduction of new Information and Communication Technologies (ICTs) components. Some simulations, using Eurostag software and a part of an IEEE New England 39 buses power system including a French type distribution network, with different cases (with a large scale of DG contributing or not in restoration process), will be shown to illustrate the DG ability in restoration process. The benefits of employing DG are also quantified.

Service restoration on distribution systems using Multi‐MicroGrids

“…Thus, a conventional strategy is exploited to restore the transmission system while the energization of some islands through DG units with black start capability will allow service restoration expansion at the downstream distribution level. The coordination between transmission and distribution restoration procedures will allow a better reliability, increasing the amount of restored load and reducing the collapsed time [15][16][17][18][19]. Concerning the MG concept, suitable control strategies for MG service restoration and subsequent islanded operation were derived in order to fully automate the entire procedure.…”

Load restoration methodology considering renewable energies and combined heat and power systems

“…Significant research has been devoted to solving the load restoration problem [15]- [24]. This problem has also been approached using the meta-heuristic algorithms [15], fuzzy technology [16], multiagent technologies [17] and other non-structured methods [2]. Authors in [19] proposed a new approach based on optimal power flow technique to minimize customer load shedding aiming to improve load pickup.…”

Fast network restoration by partitioning of parallel black start zones

“…The BS unit placement has been optimised regarding restoration efficiency in [16, 17]. Restoration under a high number of renewables has been investigated in [18].…”
