Due to the new green energy policies, district heating companies are being increasingly encouraged to exploit power-to-heat assets, e.g., heat pumps and electric boilers, in their distribution networks besides the traditional central combined heat and power units. The increased utilization of these assets will generate a more complex interaction between power distribution grids and district heating networks including markets for provision of ancillary services. Enabling the participation of power-to-heat units in the ancillary service markets, e.g., frequency reserves, may increase the revenue streams for assets' owners. However, some technical challenges must first be addressed, including optimization of portfolios of assets that accounts for ancillary service markets, new coordination and operational schemes for portfolio of assets, increase data exchange and interactions with transmission system operators, and new local control schemes for units. This paper proposes a systematic model based design approach for assessment of provision of frequency regulation by power-to-heat assets using the smart grid architecture model. The proposed approach is demonstrated in a Real-Time Control Hardware-in-the-Loop laboratory environment.

Information and Communication Technology (ICT) infrastructures are at the heart of emerging smart grid scenarios with high penetration of Distributed Energy Resources (DER). The scalability of such ICT infrastructures is a key factor for the large scale deployment of the aforementioned smart grid solutions, which could not be ensured by small-scale pilot demonstrations. This paper presents a novel methodology that has been developed in the scope of the H2020 project Integrid, which enables the scalability analysis of ICT infrastructures for smart grids. It is based on the smart grid architecture model (SGAM) framework, which enables a standardized and replicable approach. This approach consists of two consecutive steps: a qualitative analysis that aims at identifying potential bottlenecks in an ICT infrastructure;and a quantitative analysis of the identified critical links under stress conditions by means of simulations with the aim of evaluating their operational limits. In this work the proposed methodology is applied to a cluster of solutions demonstrated in the Integrid Slovenian pilot. This pilot consists of a Large Customer Commercial Virtual Power Plant (VPP) that provides flexibility in medium voltage for tertiary reserve and a Traffic Light System (TLS) to validate such flexibility offers. This approach creates an indirect Transmission System Operator (TSO)-Distribution System Operator (DSO) coordination scheme.

An Active Network Management system comprises a large number of different technical systems that interact in several ways to pursue local objectives. The smart grid architecture model was developed for the description of the coupling of these technical systems and scenarios within an Active Network Management system. In this paper, this modelling paradigm is applied for the requirements engineering and a uniform description of a cross-sectoral Active Network Management system. Essential requirements are shown and described in relation to the two upper layers of the smart grid architecture model. Based on the requirements engineering results, the implementation of a multi agent system is proposed. For the development of this multi agent system, a new software engineering paradigm is applied. Finally, the functionality use-case developed cross-sectoral Active Network system are described, which will be investigated in a later field test.

In order to systematically shift existing control and management paradigms in distribution systems to new interoperable communication supported schemes in smart grids, we need to map newly developed use cases to standard reference models like smart grid architecture model (SGAM). From the other side, any new use cases should be tested and validated ex-ante before being deployed in the real-world system. Considering various types of actors in smart grids, use cases are usually tested using co-simulation platforms. Currently, there is no efficient co-simulation platform which supports interoperability analysis based on SGAM. In this paper, we present our developed test platform which offers a support to design new use cases based on SGAM. We used this platform to develop a new scheme for wide area monitoring of existing distribution systems under growing penetration of Photovoltaic production. Off-the-shelf solutions of state estimation for wide area monitoring are either used for passive distribution grids or applied to the active networks with wide measurement of distributed generators. Our proposed distribution state estimation algorithm does not require wide area measurements and relies on the data provided by a PV simulator we developed. This practical scheme is tested experimentally on a realistic urban distribution grid. The monitoring results shows a very low error rate of about error of load forecast. Using our SGAM-based platform, we could propose and examine an Internet-of-Things-based infrastructure to deploy the use case.

Traditional electrical grids are shifting towards smart grids that could deliver electricity in sustainable, economic and secure way. Simultaneously, characteristics of electrical grids are becoming much more complex that require development of several smart grid functionalities. This thesis studies architecture modeling of smart grid Testing Platform (SGTP) and integration of MultiPower laboratory. The architecture was defined in col- laboration with research project team in a project called "Integrated business platform of distributed energy resources" (HEILA). Furthermore, the main goals are to produce an architecture model, which promotes specific smart grid related use cases, and intercon- nect the MultiPower laboratory with the platform. This thesis is divided into two parts. Firstly, background, challenges with smart grids, the HEILA project and MultiPower laboratory are introduced. Then, smart grid Archi- tecture model (SGAM) Framework, tools and related architecture definitions in different projects are studied. In addition, information models defined by IEC 61850 standard and Common Information model (CIM), smart API, HyperText Transfer Protocol (HTTP) and MQ Telemetry Transport (MQTT) protocols are studied because of their central role in the architecture model and integration. Secondly, results are presented with descrip- tions of the architecture model and integration process. The architecture model presents how different actors cooperate in order to offer and use flexibility related services on distribution level. The architecture model increases level of details, adds functionalities and changes some of the protocols used when compared to the related architectures. Additionally, self-descriptive and more flexible messaging are introduced as messages contain semantic information and they are not bound to any spe- cific format. The function positioning with two-way communications promotes decen- tralized data acquisition and control. Generally, that may

Ensuring resilient operation and control of smart grids is fundamental for empowering their deployment, but challenging at the same time. Accordingly, this study proposes a novel methodology for evaluating resilience of Information and Communication Technology (ICT) systems for smart distribution grids. Analysing how the system behaves under changing operating conditions a power system perspective allows to understand how resilient the smart distribution grid is, but the resilience of the ICT system in charge of its operation affects the overall performance of the system and does, therefore, condition its resilience. With the aim of systematising the evaluation of ICT systems' resilience, this study proposes to combine a standardized modelling of smart grids, the smart grid architecture model (SGAM), with a data structured diagram, the Entity Relationship model (ERM). The architecture of smart distribution grids is analysed through SGAM. Then, their technical characteristics and functionalities are defined and represented in a ERM diagram. Finally, the attributes or properties of the system components are used to formulate resilience indicators against different types of disturbances. This methodology is then applied to analyse the resilience of a ICT platform being developed in EMPOWER H2020 project.

The rollout of smart grid solutions has already started and new methods are deployed to the power systems of today. However, complexity is still increasing as focus is moving from a single system, to a system of systems perspective. The results are increasing engineering efforts and escalating costs. For this reason, new and automated engineering methods are necessary. This paper addresses these needs with a rapid engineering methodology that covers the overall engineering process for smart grid applicationsfrom use case design to deployment. Based on a model-driven development approach, the methodology consists of three main parts: use case modeling, code generation, and deployment. A domain-specific language is introduced supporting the use case design according to the smart grid architecture model. It is combined with the IEC 61499 distributed control model to improve the function layer design. After a completed use case design, executable code and communication configurations (e.g., IEC 61850) are generated and deployed onto compatible field devices. This paper covers the proposed rapid engineering methodology and a corresponding prototypical implementation which is validated in a laboratory experiment. Compared to other methods the proposed methodology decreases the number of engineering steps and reduces the use case design and implementation complexity.

Engineering Support for Handling Controller Conflicts in Energy Storage Systems Applications

ENERGIES 2017年第10期10卷 1595-1595页

Energy storage systems will play a major role in the decarbonization of future sustainable electric power systems, allowing a high penetration of distributed renewable energy sources and contributing to the distribution network stability and reliability. To accomplish this, a storage system is required to provide multiple services such as self-consumption, grid support, peak-shaving, etc. The simultaneous activation of controllers operation may lead to conflicts, as a consequence the execution of committed services is not guaranteed. This paper presents and discusses a solution to the exposed issue by developing an engineering support approach to semi-automatically detect and handle conflicts for multi-usage storage systems applications. To accomplish that an ontology is developed and exploited by model-driven engineering mechanisms. The proposed approach is evaluated by implementing a use case example, where detection of conflicts is automatically done at an early design stage. Besides this, exploitable source code for conflicts resolution is generated and used during the design and prototype stages of controllers development. Thus, the proposed engineering support enhances the design and development of storage system controllers, especially for multi-usage applications.

In nowadays smart grids, economic optimizations performed by Virtual Power Plants (VPPs) may interfere with stable grid operation required by Distribution System Operators (DSOs). Since smart grids and VPPs are important building blocks of future energy systems, bridging the gap between economic optimization performed by VPPs and stable grid operation required by DSOs is an important task. In this paper, we present a fundamental system architecture and a concept enabling VPPs and DSOs to negotiate their positions to satisfy the needs and requirements of both sides. Thus, instead of being a potential interference factor, economically sensible operation of distributed energy resources (DERs) organized in VPPs and stable grid operation as required by DSOs are integrated in a common solution.

This paper describes the impact of ICT on the future development of pan-European power systems up to the 2050 time horizon. More innovative power delivery, supported by state-of-the-art ICT, is essential for the future development of low-carbon and more extensively integrated power systems. The most physically quantifiable ICT components: storage, bandwidth, and computational power are introduced alongside the appropriate qualitative ICT objectives of resilience, maintenance, privacy and cyber security, and interoperability. Relevant ICT infrastructures are classified and these infrastructures are mapped to the power system domains in order to illustrate their interactions and domain relevance. Finally, in order to consider the role of ICT infrastructure in future scenarios, a range of potential benefits that ICT can bring into future power systems are quantified, and the costs of implementing ICT infrastructures and benefits enabled through ICT are compared for a specific scenario.
