Experimental Demonstration of Buildings Providing Frequency Regulation Services in the Swiss Market

Colin Neil Jones, Tomasz Tadeusz Gorecki, Faran Ahmed Qureshi, Luca Fabietti

This paper investigates the potential of commercial buildings to offer ancillary services to the grid. We consider a tracking procurement inspired by secondary frequency control, where the resource needs to commit to a nominal consumption profile ahead of ...

Interior Point Decomposition for Multi-Agent Optimization

Colin Neil Jones, Ivan Pejcic, Altug Bitlislioglu

In this paper we present the application of the interior-point decomposition (IPD) method, which was originally formulated for stochastic programming, to optimization problems involving multiple agents that are coupled through constraints and objectives. I ...
