Flexible co-operation of TCSC and corrective topology control under wind uncertainty : an interval-based robust approach
This paper presents an AC optimal power flow (AC-OPF) model including flexible resources (FRs) to handle uncertain wind power generation (WPG). The FRs considered are thermal units with up/down re-dispatching capability, ...
Application of opportunistic information-gap decision theory on demand response aggregator in the day-ahead electricity market
The proposed model analyzes the profit of a demand response (DR) aggregator from trading DR in the day-ahead electricity market in a way that it tends to gain profit from the favorable deviations of the uncertain parameters. ...
Co-optimization of transmission switching and variable reactance devices control under worst-case wind uncertainty
The work reported in this paper jointly addresses two major challenges in modern power systems: 1) systematically maximizing wind power generation (WPG) utilization under worst-case uncertainty and 2) employing mixed ...
A risk-based decision framework for the distribution company in mutual interaction with the wholesale day-ahead market and microgrids
One of the emergent prospects for active distribution networks ( DN ) is to establish new roles to the distribution company ( DISCO ). The DISCO can act as an aggregator of the resources existing in the DN , also when parts ...
Power system flexibility improvement with a focus on demand response and wind power variability
Unpredictable system component contingencies have imposed vulnerability on power systems, which are under high renewables penetration nowadays. Intermittent nature of renewable energy sources has made this unpredictability ...
Impact of distributed generation on protection and voltage regulation of distribution systems : a review
During recent decades with the power system restructuring process, centralized energy sources are being replaced with decentralized ones. This phenomenon has resulted in a novel concept in electric power systems, particularly ...
Multi-objective optimisation method for coordinating battery storage systems, photovoltaic inverters and tap changers
The many well-established advantages of distributed generation (DG) make their usage in active distribution networks prevalent. However, uncontrolled operation of DG units can negatively interfere with the performance of ...
An optimal approach for load-frequency control of islanded microgrids based on nonlinear model
Due to the increased environmental and economic challenges, in recent years, renewable based distribution generation has been developed. More penetrations from the side of consumers caused a new concept called microgrids ...
Multiobjective ray optimization algorithm as a solution strategy for solving non-convex problems : a power generation scheduling case study
Economic generation scheduling (EGS) is a non-convex optimization problem for allocating optimal generation among the committed units that can meet given real-world practical limits such as ramp rate limits, prohibited ...
Energy management strategy in dynamic distribution network reconfiguration considering renewable energy resources and storage
Penetration of renewable energy sources (RESs) and electrical energy storage (EES) systems in distribution systems is increasing, and it is crucial to investigate their impact on systems’ operation scheme, reliability, and ...
