The main components used for integration in the power system of distributed renewable energy sources, basically work in dc, f.i. batteries, photovoltaic systems and fuel cells. In addition, most common loads already use dc power internally, usually provided by rectifiers. Consequently, the usage of generated energy can be made more effective if directly delivered to load through a dc grid or microgrids, with improvements in efficiency, costs and reliability. The HVDCs are already widely used for their convenience over long-distance bulk power transmission. Despite this wide usage of the dc power network, the Power Quality definition and assessment in dc is still in an unstandardised situation. This paper focuses on a specific PQ phenomenon typical of dc networks: voltage ripple. Observations are made on the sources of this phenomenon and a methodology is proposed for measuring the intensity of this disturbance by introducing synthetic indices, also with reference to the most recent technical standards, with the specific scope to the compatibility level assessment. The proposed measurement techniques are applied to experimental data acquired on the power supply of a dc railway system.

With the development of Smart Grids, unconventional voltage transformers known as Low Power are being widely deployed in medium voltage power networks for measurement and protection functions. Low power voltage transformers, referred to as voltage sensors, are prone to the parasitic coupling of electric fields which may disturb the voltage measurement. In this work, an electrical equivalent model of the voltage sensor embedded in Smart Bushing is suggested for estimating the immunity versus electric fields present in Gas Insulated Switchgears. In addition, a setup is designed to test the immunity under different scenarios.

In recent years, electricity grids have undergone radical transformations in order to manage the increasing presence of Distributed Energy Resources (DER) as well as the increasing demand for electricity due to electric vehicle charging systems. The IEC 61850 standard, which introduced digital control architectures based on communication networks, marked a significant milestone in the management of primary substations and the entire electrical network in general. The Stand Alone Merging Units (SAMUs) are the elements that connect the analog sensors installed on the electrical network to the digital control systems of substations. The digitalization performed by SAMUs enables the virtualization of measurement and control functions, which are typically operated by dedicated components. The accuracy of information obtained from a distributed system, such as SAMUs, depends on the system’s ability to synchronize with an external source of time. Typically, SAMUs are synchronized via Global Positioning System (GPS) or networked solution, such as IEEE 1588. A novel wireless clock distribution method based on Ultra Wide Band (UWB) technology is presented and evaluated in this research. The experimental characterization highlights as the proposed approach is a feasible solution for clock synchronization of SAMUs: the phase error of clocks generated by two SAMUs synchronized via UWB is 17.5 ns.

The problem of Optimal Phasor Measurement Units (PMU) Placement (OPP) in power systems is usually driven just by cost issues, whereas less attention is paid to measurement-related aspects. In particular, most OPP strategies rely on the minimization of a single objective function including system observability constraints, with no attention to state estimation performance. In fact, the observability constraints (either with or without redundancy due to contingencies) are not enough to ensure that the uncertainty associated with system state estimation is adequate for the intended purpose. For this reason, in this paper the OPP problem is addressed by minimizing two contrasting objective functions, i.e., the classic PMU deployment costs and the maximum system state estimation uncertainty. The aforementioned bi-objective OPP formulation is solved through a Non-dominated Sorting Genetic Algorithm II (NSGA-II). The results obtained applying the proposed approach to the IEEE 14-bus and 57-bus test systems show that several trade-off solutions can be found in different scenarios both with and without considering contingencies due to line or PMU faults. Among the Pareto-optimal solutions, the most interesting ones are probably those that ensure the highest normalized System Observability Redundancy Index (SORI) per PMU and those that minimize both estimation uncertainty and cost in all scenarios.

The need for accurate measurements is daily increasing and recognized by system operators. Whether this aspect may be less significant for transmission networks (TNs), the same is not true for the distribution one (DN). In fact, the investments dedicated to TNs are far higher compared to those for DNs. Therefore, this work deals with the accuracy requirements needed in DNs to achieve significant measurement results. In particular, the study starts from the hypothesis that measurements are collected from typical current and voltage sensors and computed via phasor measurement units. The work first describes the typical characteristics of the DN. Second, the sources of uncertainty that contribute to the overall uncertainty of the output quantities (module and phase of currents and voltages) are detailed and analyzed. Finally, the Monte Carlo method has been applied to quantify the uncertainty of those quantities in a variety of realistic DN configurations. From the results, it emerges the significance of the measurement chain design due to its significant impact on the accuracy of the measured quantities.

Harmonic filter bank performance could be affected by network configuration changes. Assessment of filter performance in a distribution network with different distortion sources and dynamic configuration states is needed for evaluation of contractual obligations on harmonic emission. By using aggregated harmonic phasors and identifying the range of harmonic phase angles where the filter causes secondary cancellation of the harmonic voltage phasor, a practical methodology that track harmonic filter performance is proposed. Application is demonstrated by means of field data.

In current power systems, Phasor Measurement Units and Phasor Data Concentrators are the main elements of the Wide Area Monitoring System. Transmission Systems Operators (TSOs) are interested in upgrading the monitoring system to implement Wide Area Monitoring Protection and Control (WAMPAC) applications. In this context, the time constraints are critical, so latency of WAMPAC systems needs to be properly considered and characterized. Following this necessity, this paper explores the latency characteristics of a WAMPAC prototype developed by the Italian TSO through an ad-hoc real-time characterization system specifically designed. The instrument is firstly metrologically characterized and then used for an experimental campaign in a real-world WAMPAC.

Synchrophasor measurements have traditionally been reserved for monitoring the operation of transmission systems. With significant developments occurring in distribution networks, specifically the integration of renewable power plants (RPPs), synchrophasor monitoring at distribution level have become of interest. To apply synchrophasors in distribution networks high precision angular recordings with accurate clock synchronization are required, termed micro-synchrophasors. A goal of micro-synchrophasor application on RPP integration is to extract small signal stability information to enable a better understanding of the dynamic phenomena when sources of renewable energy integrate with the distribution system. This paper evaluates synchrophasors at a 75 MW Photovoltaic (PV) plant connected to a 132 kV distribution network in the South African power system.
