Congestion is a major limiting factor preventing expansion of renewable energy production in distribution networks. However, with large shares of connected power electronic-interfaced generators in combination with new types of controllable loads, such as electric vehicles (EVs), there is a potential to greatly increase network operation flexibilit...
The transition to Smart Grids increases the complexity of power grids by involving many more interdependent actors and integrating additional information and communications technology. To provide a common basis for Smart Grid data representation and exchange, the standardized Common Information Model (CIM) has been introduced and extended, i. a., b...
To be able to limit the temperature increase to clearly under 2 ℃ above pre-industrial levels, the European Union and Germany in particular are facing profound change in their energy system in the coming years. The end of coal-fired power generation, the coupling of different sectors (e.g. electricity, heat, mobility…) and the associated digitizati...
Modern distribution grids are complex systems that need advanced management for their secure and reliable operation. The Information and Communication Technology domain today offers unprecedented opportunities for the smart design of tools in support of grid operators. This paper presents a new philosophy for the digitalization and automation of di...
Modelling the fast dynamics of power converters is of growing concern in power grids and Microgrids. Dynamic phasor (DP) concept has been widely applied to switched power converter for modelling fast transients efficiently due to the inherent frequency shift property of DPs. The dynamics introduced by the DC/AC power converters depend on the contro...
New types of power system transients with lower time constants are emerging due to the replacement of synchronous generation with converter interfaced generation and are challenging the modeling approaches conventionally applied in power system simulation. Quasi-stationary simulations are based on classical phasor models, whereas EMT simulations ca...
This paper presents an overview of the objectives and conceptual approach of the research and development activities in the ANM4L project.
Real-time simulation is an increasingly popular tool for product development and research in power systems. However, commercial simulators are still quite exclusive due to their costs and they face problems in bridging the gap between two common types of power system simulation, conventional phasor based, and electromagnetic transient simulation. T...
The management and transmission networks is becoming increasingly complex due to the proliferation of renewables-based distributed energy resources (DER). Existing control systems for DER are based on static specifications from interdependent network connection documents. Such systems are inflexible and their maintenance requires concerted effort b...
DPsim is a real-time capable solver for power systems that operates in the dynamic phasor and electromagnetic transient (EMT) domain. This solver primarily targets co-simulation applications and large-scale scenarios since dynamic phasors do not require sampling rates as high as EMT simulations do. Due to the frequency shift introduced by the dynam...
Over the last decade, the Common Information Model (CIM), as specified by IEC 61970 / 61968, has become an important document format for the storage of power grid data. Its object-oriented design makes it easily maintainable and extensible for many use cases in the energy sector. As a result, more and more power grid analysis and simulation tools a...
Smart grids evolve rapidly towards a system that includes components from different domains, which makes interdisciplinary modelling and analysis indispensable. In this paper, we present a cosimulation architecture for smart grids together with a comprehensive data model for the holistic representation of the power system, the communication network...
This paper presents an overview of the portion of the real-time simulation laboratory of the Institute for Automation of Complex Power Systems at RWTH Aachen University, dedicated to the testing of instrumentation, measurement and monitoring applications. Its key feature is the ability to test monitoring systems and complex monitoring methods as in...
This paper presents a noninvasive online parametric identification of three-phase AC power impedances to assess small-signal stability of grid-tied inverter systems by using well-known impedance-ratio-based stability criteria. The identification technique is integrated into the control of an existing grid-tied inverter for the estimation of wide ba...
The increasing complexity of ICT systems in smart grids requires that all actors improve their interoperability. To this aim, IEC 61970/61968 specify the Common Information Model (CIM) which describes terms in the energy sector and relations between them. One of the key features of CIM is its object-oriented design based on the Unified Modeling Lan...
The increasing use of energy from renewable sources will entail significant changes in power systems. On the generation as well as the load side more and more power electronics devices are in operation, resulting in an increase of harmonics in the power systems. For simulating modern power systems, linear steady-state modeling approaches like singl...
The increment of distributed energy resources such as small photovoltaic plants or micro-cogeneration systems, together with the increase of electric vehicles connected to the grid, are bringing new challenges to distribution system operators (DSOs). In order to support DSOs to face such new challenges, this paper proposes a new solution based on a...
This paper presents a low-cost, re-configurable Modular Intelligent Node for Distribution systems (MIND). It can serve as a sustainable and general-purpose module for monitoring and automation of power distribution systems. MIND is designed and built with low-cost hardware, interconnectivity with other modules, and highly reconfigurable design of h...
The increasing presence of renewables in today's power systems leads to more power electronics devices. Therefore, it is becoming critical to integrate analysis and design of power electronics and power systems. This paper presents a multi-level approach to use Modelica models to interface these two domains and to enable experts to work with consis...
The increment of Distributed Energy Resources – DERs – such as small photovoltaic plants or micro-cogeneration systems together with the increase of Electric Vehicles connected to the grid are bringing new challenges to the Distribution System Operators – DSOs. In order to support DSOs to take on these new challenges it is proposed a new framework...
This paper investigates the use of adaptive backstepping as a decentralized control strategy for voltage stability of DC microgrids where the loads and generators are interfaced through power electronic converters. The stabilizing control of the bus voltages resides in the generation side interfacing converters. The loads are tightly regulated and...
In future all-electrical ships with Medium Voltage DC distribution, the power system stability can be jeopardized by the presence of constant power loads, due to the negative impedance characteristic of their tightly regulated converters. In order to solve this problem we apply backstepping as a nonlinear control technique to the converter interfac...
