Implementation issues on the design of current loops based on resonant regulators for isolated microgrids

This paper analyzes the influence of state feedback coupling between the capacitor voltage and inductor current in voltage source inverters (VSI) operating in stand-alone microgrids. A decoupling technique is proposed as an effective measure to enhance the ...

Large Scale Deployment of PV Units in Existing Distribution Networks: Optimization of the Installation Layout

Mario Paolone, Michael Lehning, Fabrizio Sossan, Annelen Kahl, Stuart John Bartlett, Jana Darulová

In fixed PV installations, the azimuth and tilt of the panels are normally chosen with the objective of maximizing the plant capacity factor. In this paper, we show that when considering distribution networks with densely clustered PV plants, there exist i ...

Fixed-structure Control of LTI Systems with Polytopic-type Uncertainty

Mahdieh Sadat Sad Abadi

This thesis focuses on the development of robust control solutions for linear time-invariant interconnected systems affected by polytopic-type uncertainty. The main issues involved in the control of such systems, e.g. sensor and actuator placement, control ...

Kron reduction methods for plug-and-play control of AC islanded microgrids with arbitrary topology

Giancarlo Ferrari Trecate

In this paper, we provide an extension of the scalable algorithm proposed in (Riverso et al., 2015) for the design of Plug-and-Play (PnP) controllers for AC Islanded microGrids (ImGs). The method in (Riverso et al., 2015) assumes DGUs are arranged in a loa ...

Energy and Reserve Management in Interconnected Systems including Electric Railway and Public Power Grids

Mokhtar Bozorg

For historical reasons, the frequency of Electric Railway Power System (ERPS) in central European countries (e.g., Switzerland, Germany and Austria) is different from the frequency of the public power grid. To feed such a low frequency (i.e., 16.7 Hz) syst ...

Providing ancillary service with commercial buildings: the Swiss perspective

Colin Neil Jones, Ioannis Lymperopoulos, Faran Ahmed Qureshi, Ali Ahmadi Khatir, Xuan Truong Nghiem

Ancillary services constitute the cornerstone of the power grid. They allow for an efficient system operation, provide resilience to uncertainties and establish safeguards against unprecedented events. Their importance is growing due to the rise of grid de ...

Stochastic frequency reserve provision by chance-constrained control of commercial buildings

Maryam Kamgarpour, Xiuwei Zhang

Robust programs with modulated uncertainty sets are problems in which the uncertainty sets are treated as optimization variables. In many applications, these uncertainty sets can be interpreted as reserve capacities for which rewards are offered. One examp ...
