Evaluating maximum wind energy exploitation in active distribution networks

Abstract

Abstract:The increased spreading of distributed and renewable generation requires moving towards active management of distribution networks. In order to evaluate maximum wind energy exploitation in active distribution networks, a method based on a multi-period optimal power flow analysis is proposed. Active network management schemes such as coordinated voltage control, energy curtailment and power factor control are integrated in the method in order to investigate their impacts on the maximisation of wind energy exploitation. Some case studies, using real data from a Danish distribution system, confirmed the effectiveness of the proposed method in evaluating the optimal applications of active management schemes to increase wind energy harvesting without costly network reinforcement for the connection of wind generation.

Active distribution networks planning with high penetration of wind power

“…ANM schemes can increase the operation 5 of the assets of network that allow the distribution networks to accommodate more DGs within the existing infrastructure and therefore, defer or avoid expensive network upgrades. The main ANM schemes include coordinated voltage control (CVC) of on load tap changers (OLTCs) and voltage regulators, adaptive power factor control (PFC) of DGs and energy curtailment [5][6][7].…”

An Optimal Procedure for Sizing and Siting of DGs and Smart Meters in Active Distribution Networks Considering Loss Reduction

“…In this way, versatile types of intelligent electronic devices (IEDs) such as distribution remote terminal units (DRTUs) and smart meters (SMs) have been developed to yield an online and efficient control on ADNs ingredients. ADNs are characterized with both renewable-based and controllable diesel-based DGs, responsive loads and flexible network structures realized with remotely controlled switches [10][11][12][13]. The active participation of end-side consumers in demand response programs (DRPs) could be divided mainly in two folds encompassing incentive-based programs and time-based programs [14][15][16].…”

“…Reference [8][9][10][11] introduce the research progresses, key technologies and challenges of ADN, summarize the necessity and feasibility to develop the ADN. Reference [12][13][14][15][16] propose to improve the interconnected DG capacity of distribution system through Active Power Flow Management (APFM). Reference [16] evaluates the maximum wind energy exploitation in ADN based on a multi-period optimal power flow (OPF).…”
