Locating distributed generator in the LMP-based electricity market for social welfare maximization

Gautam, Durga; Mithulananthan, Nadarajah - 2007

This article presents two new methodologies for the optimal placement of distributed generation (DG) in an optimal power flow (OPF) based wholesale electricity market. DG is assumed to participate in the real time wholesale electricity market. The problem of optimal placement, including size, is...

Wind energy generators sitting and sizing based on uncertain generation pricing

Mota, Alexandre De Assis; Mota, Lia T.M. - In: International Journal of Global Energy Issues 32 (2009) 3, pp. 260-277

This paper proposes a methodology for sitting and sizing wind distributed generators (WDGs). These generators are characterised by an uncertain active power production due to the random behaviour of the wind speed. The uncertain generation directly impacts the network total generation cost and...

Lying generators: Manipulability of centralized payoff mechanisms in electrical energy trade

Csercsik, Dávid - 2015

Optimal power flow (OPF) problems are focussing on the question how a power transmission network can be operated in the most economic way. The general aim in such scenarios is to optimize generator scheduling in order to meet consumption re-quirements, transmission constraints and to minimize...
