This paper proposes a design pattern based on the service-oriented architecture for the design of flexible distributed automation control system for substation automation systems. The design pattern is intended to be applied to control systems based on the leading standards for software development of smart grid: IEC 61850 and IEC 61499. The proposed design pattern models system requirements as orchestrators...
This paper proposes a novel method of modelling requirements for smart grid automation systems that fits and complements the leading standards used for software development in smart grid: IEC 61850 and IEC 61499. Ontological representation is used to formally model the systems requirements and the integration of the requirement modelling to be used in conjunction with IEC 61850 specifications and...
This paper presents an automatic software generation method for energy distribution automation. The method uses the distribution network structure represented in SCL format of the IEC 61850 standard and generates complete executable applications compliant with the IEC 61499 standard. Each equipment element is based on the componentized MVC design pattern and can be executed on a distributed network...
The so called Smart Grid is said to be enabled with bi-direction communication networks and energy flow. IEC 61850 is a substation communication standard which improves interoperability of the substation design. IEC 61499 is an automation standard which can be used for implementation of control in IEC 61850 models. This work is utilizing Model Driven Engineering techniques for substation automation...
The paper aims at demonstrating the feasibility of an execution platform that is capable of performing protection and control functions from various vendors in a controlled manner. This will reduce vendor dependency enabling utilities to standardize hardware while implementing complex protection schemes from multiple vendors at reduced cost. The paper develops protection system including earth, differential...
A district heating grid is a hot water pipeline grid used to transmit waste heat from CHP (Combined Heat and Power) production plants to buildings, where it is used for service water and space heating. Currently, broad use of district heating is limited to Northern Europe and some regions in Central Europe, but the European Union Energy Efficiency Directive 2012/27/EU and Energy Performance of Buildings...
This paper presents the analysis and simulation of the performance of fault location and isolation (FLI) in an automated power distribution feeder. This system is composed of two coupled networks: a power system consisting of a distribution feeder with multiple load buses, and an unreliable communication network of the distributed intelligent agents in the system, namely, the substation automation...
This paper presents an introductory step in the automatic generation of distributed control software for power distribution automation systems based on Ontology Driven Engineering enabled by industrial standards IEC61850 and IEC61499. The novelty of this approach is the ability of automatically generating the logical connections between the logical nodes. The paper covers the several stages of the...
This paper presents a practical framework to bring the cyber-physical block diagram models, such as Ptolemy, to the practice of industrial automation. Cyber-Physical Component (CPC) architecture is suggested. CPC aims at the improvement of design, verification and validation practices in automation of Smart Grid. IEC 61499 standard is used as a basis for this architecture. This architecture addresses...
The reliability theory used in the design of complex systems including electric grids assumes random component failures and is thus unsuited to analyzing security risks due to attackers that intentionally damage several components of the system. In this paper, a security risk analysis methodology is proposed consisting of vulnerability analysis and impact analysis. Vulnerability analysis is a method...
The paper proposes a novel computer-aided model-based system engineering process for Smart Gird applications. The process is supported by the SysGrid tool that plays the roles of system configurator and device configurator. The design process starts with single line diagrams which are automatically transformed to executable function block specifications. The process is based on the Smart Grid control...
The electric energy system is changing more and more into a Smart Grid. A key technology in order to transform the actual grid is the information and communication technology. This means that advanced management, automation, control and communication concepts and systems have to be developed in order to cope with changing and challenging future requirements in the intelligent grid; especially the...
In this paper we present a prototypical smart metering infrastructure (MI) as part of the “distributed nervous system of SmartGrid”. Proposed MI is enabled with distributed programming infrastructure of the international standards IEC 61499, communication and design infrastructure of IEC 61850. The paper introduces IEC 61850 logical device for the smart meter. Based on this definition, the intelligent...
