A Novel Reduced Model for Electrical Networks with Constant Power Loads
Nima Monshizadeh, Claudio De Persis, Arjan J. van der Schaft +1
We consider a network-preserved model of power networks with proper algebraic constraints resulting from constant power loads. Both for the linear and the nonlinear differential al…
Bisimulation equivalence of DAE systems
Noorma Yulia Megawati, Arjan van der Schaft
In this paper the notion of bisimulation relation for linear input-state-output systems is extended to general linear differential-algebraic (DAE) systems. Geometric control theory…
Modeling of Physical Network Systems
A. J. van der Schaft
Conservation laws and balance equations for physical network systems typically can be described with the aid of the incidence matrix of a directed graph, and an associated symmetri…
A unifying energy-based approach to optimal frequency and market regulation in power grids
Tjerk Stegink, Claudio De Persis, Arjan van der Schaft
In this paper we provide a unifying energy-based approach to the modeling, analysis and control of power systems and markets, which is based on the port-Hamiltonian framework. Usin…
A Port-Hamiltonian Approach to Optimal Frequency Regulation in Power Grids
Tjerk Stegink, Claudio De Persis, Arjan van der Schaft
This paper studies the problem of frequency regulation in power grids, while maximizing the social welfare. Two price-based controllers are proposed; the first one an internal-mode…
A Communication-Free Master-Slave Microgrid with Power Sharing
Pooya Monshizadeh, Claudio De Persis, Nima Monshizadeh +1
In this paper a design of a master-slave microgrid consisting of grid-supporting current source inverters and a synchronous generator is proposed. The inverters are following the f…
Consensus problems with arbitrary sign-preserving nonlinearities
J. Wei, A. R. F. Everts, M. K. Camlibel +1
This paper studies consensus problems for multi-agent systems defined on directed graphs where the consensus dynamics involves nonlinear and discontinuous functions. Sufficient con…
