“…Such bitrates are not easily manageable, for example, by narrowband power line communications [27] adopted for automatic meter reading, advanced metering infrastructure and other applications. Several pioneer projects are ongoing to define full communication infrastructures for MV/LV DNs, that are expected to be hybrid [28] (power line, wireless and optical fiber technologies) and hierarchical [29].…”

Distribution System State Estimation (DSSE) is an essential tool for the management and control of future distribution networks. Distribution grids are usually characterized by a very large number of nodes and different voltage levels. Moreover, different portions of the system can be operated by different Distribution System Operators. In this context, multiarea approaches are key tools to efficiently perform DSSE. This paper presents a novel approach for Multi-Area State Estimation in distribution systems. The proposed algorithm is based on a twostep procedure, where the first-step local estimations are refined through a newly designed second step that allows the integration of the measurement information available in the adjacent areas. The main novelty in this paper is the mathematical analysis of the impact brought by possible measurements shared among different areas, which drives the design of a new efficient Weighted Least Squares formulation of the second step to maximize the achievable estimation accuracy. Tests performed on the unbalanced IEEE 123-bus network prove the goodness of the new multiarea estimator proposed and show the accuracy and efficiency enhancements obtainable with respect to previous literature.

“…Considering the challenges faced by DNs, a first step to improve their automation level has consisted in adding a local supervisory system in PSs [14], [15]. Thus, a first decentralization of the network monitoring and control system has been implemented at the HV/MV level.…”

“…Due to the growing complexity related to the generation and consumption patterns at the LV level, monitoring and control issues concerning this level of the DN are becoming more relevant, being the focus of various DSOs research and development activities [12], [13], [15]. The SMs, recently being installed at the customer premises in various countries, represent an opportunity to enable advanced monitoring of the LV grid.…”

The deepening penetration of Distributed Energy Resources (DERs) into Distribution Networks (DNs) is causing relevant issues to be addressed by Distribution System Operators (DSOs), such as quality of service, security and safety, both at Medium Voltage (MV) and Low-Voltage (LV) distribution levels. This paper presents how A2A Reti Elettriche SpA, an Italian DSO, had addressed those challenges launching a set of research activities in different areas of the distribution automation. Results collected during field experiences have been used to design the reference model of the next generation of DN Secondary Substations (SS).

“…Smart meter data play a significant role in the smart grid. For instance, they can be used for (Low Voltage) LV network monitoring and can give feedback for the LV grid condition, as is done in [8] along with secondary substation measurements. In [9] smart meter measurements are used for low voltage grid state estimation; the authors proposed a cloud-based smart metering architecture, which allows scalability and interoperability for the meters.…”

Design of Experiments in the Methodology for Interoperability Testing: Evaluating AMI Message Exchange

et al. 2019

Interoperability is a challenge for the realisation of smart grids. In this work, we apply the methodology for interoperability testing and the design of experiments developed at the Smart Grids Interoperability Laboratory of the Joint Research Centre of the European Commission on a simple use case. The methodology is based on the Smart Grid Architecture Model (SGAM) of CEN/CENELEC/ETSI and includes the concept of Basic Application Profiles (BAP) and Basic Application Interoperability Profiles (BAIOP). The relevant elements of the methodology are the design of experiments and the sensitivity/uncertainty analysis, which can reveal the limits of a system under test and give valuable feedback about the critical conditions which do not guarantee interoperability. The design and analysis of experiments employed in the Joint Research Centre (JRC) methodology supply information about the crucial parameters that either lead to an acceptable system performance or to a failure of interoperability. The use case on which the methodology is applied describes the interaction between a data concentrator and one or more smart meters. Experimental results are presented that show the applicability of the methodology and the design of experiments in practice. The system is tested under different conditions by varying two parameters: the rate at which meter data are requested by the data concentrator and the number of smart meters connected to the data concentrator. With this use case example the JRC methodology is illustrated at work, and its effectiveness for testing interoperability of a system under stress conditions is highlighted.
