Reactive power provision is an essential ancillary service, which opens up many opportunities for different actors of power system. This reactive power is essential to cope up for the inductive capacitive effects of the long transmission lines, and due to the varying nature of the loads. The reactive power management leads to voltage stability, and thus the paper deals with the review of the most common procedures for the compensation of reactive power. The paper then develops a model for a coal-fired power plant, and then compares the performance of different compensation techniques in terms of costs, efficiency in terms of real power losses, and performance capability in terms of response time and amount of reactive power. The paper then realizes the trade-off between different techniques, and then an aggregation of different techniques are used to strategize the coordinated control of techniques with respect to the requirements. Finally, a topology of this coordinated control mechanism is developed in accordance with the Italian regulations.

Nowadays the electric power system is facing new challenges related to the integration of renewable sources, more and more frequently combined with energy storage systems. The use of these technologies is very promising, although it requires sophisticated control architectures in order to successfully balance the intermittence and unpredictability of renewables, and provide the power grid with new services. The presence of a storage state estimator is absolutely required to correctly identify the storage performance and present conditions, in terms of stored energy, aging or possible failures; this is crucial to assess the real exploitability of the battery, both during its first or second life application. This paper focuses in particular on aging mechanisms, describing and comparing three possible models and their deployment procedures. Flexibility of implementation, accuracy in aging determination, and ease of use of each technique have been deeply analysed and compared.

This paper describes how the voluntary initiatives amongst European TSO's have evolved into Regional Security Coordination (RSC), partly based on binding TSO agreements and partly through legal requirements in the European Network Guidelines. The regional coordination creates the first significant step in the digitalization of the Pan-European electricity transmission system through common access to standardized data for the entire European Power System and the standardized use of data for operational security calculation and operational planning. Such access to extensive, reliable, common and shared power system data for several timeframes is a key condition for the regional coordination. The paper describes how this condition is fulfilled through the development of standardized datasets from all TSO's, Individual Grid Models (IGM), based on a common standard, Common Grid Model Exchange Standard (CGMES), how the IGM's are merged to Common Grid Models (CGM) for the entire Power System and further how the RSC's through standardized regional business processes supports the TSO's to operate the European transmission grid safely and to its limits. Finally, the paper discusses the further outlook and the expectations for enhancement of RSC activities towards 2025 including the possibilities for digital innovation based on the availability of big data from the power system.

The development of HVDC (high voltage direct current) systems closely follow the growth of global energy requirements. In particular, HVDC cables are conveniently used for the interconnection of geographical areas which need a low environmental impact and/or when submarines interconnections have to be built up. The paper investigates the stored energy value in an HVDC cable during its normal duty and if it is possible to take advantage of this energy when the cable is disconnected for some reason. In particular, the idea is to store the cable energy, which would be dissipated uselessly, by using a dedicated system and then reuse it when favorable conditions hold, e.g a convenient economic scenario in the electricity market context. An hypothesis on the use of a superconducting magnetic energy storage (SMES) device as storage system is investigated and the shown simulation results confirm the validity of the proposed idea.

Building energy simulation is an effective tool to design retrofit and management interventions, provided that the simulation model is carefully calibrated. As a first step towards the development of guidelines for using dynamic simulation for the design of retrofit interventions aiming at the nZEB target, in the present study a calibration procedure, consisting in tuning the building walls model first, is demonstrated. Therefore, starting from a real building case study, the walls model is created in parallel within different building simulation environments, namely EnergyPlus, IDA ICE and OpenBPS. The impact of the simulation tool and of the calibration procedure on the model predictions is thus investigated and discussed.

The integrative effect of the glare will be studied in this paper, developing a non-invasive measurement system. The authors propose a measurement system based on an embedded system, Raspberry PI3, with a PI camera, but also with a GPS shield and RGB sensor, type TCS34725. The RGB sensor is used in a luminance meter configuration, in order to investigate the average luminance of the visual field.

Overvoltages occuring in High Voltage Direct Current (HVDC) links during pole to ground faults of Modular Multilevel Converters (MMC-HVDC) differ significantly from the normative switching impulse (SI) or normatively predefined slow front overvoltage waveforms. Knowledge on insulation system behaviour under consideration of those non-standard impulses is rare. However, for insulation coordination strategies of MMC-HVDC, this information gains in importance in order to determine insulation worst case stresses. For this purpose, a suitable and scalable laboratory test setup for the imitation of expected MMC-HVDC transient stresses is presented. Besides the presentation of a theoretically modelling approach and basic circuit design rules, a small scale laboratory realization is presented and obtained results are discussed. This setup is scalable and suitable for future investigations on related dielectric effects caused by those non-normative impulses.

Mold heating is an important key factor for the mold cycle which affects the quality of the molded product. The involved molding processes regards polymers foaming, plastics injection, or resin-curing with composites. While the manufacturing cycle of plastics injection molding requires a heating/cooling system, other processes do not require the cooling phase. Polymers foaming and resin-curing require specific values of temperature to provide full chemical reactions and a good product quality on the surface. Induction heating systems are suitable for such applications; however, many industrial cases require customized solutions to support the molding cycle of different parts. A temperature control is always mandatory to reduce the energy cost and increase the heating efficiency. This paper studies a molds temperature control applied in the polyurethane foaming of footwear soles. The proposed induction heating system and its control have been studied using the Hardware-In-the-Loop simulations. Due to a high mold thermal inertia, which increases the mold temperature even if the control system turns off the thermal power, tailored controllers have been analyzed to achieve the desired temperature set-point. The thermal model of the foaming mold and the induction heating system have been modelled and developed in the MATLAB/Simulink® framework. An ATMEGA processor was used to implement and test a discrete PID controller while Simulink induction-heating system model was running, creating an Hardware-In-The-loop platform.

The Internet of Things for the household market will reach 1.7 trillion dollars by 2020. With fast growing innovation trends an important challenge consists in finding optimized algorithms for data prediction and interpretation. Building's energy behavior is influenced by a wide range of factors. The complexity of predicting the energy performance of the buildings has led to simplified models which use regression technics based on input-output relations. The current research is focused on finding an optimized Hidden Markov Model which fits the data acquired through IoT system. The current paper is motivated by the necessity of identifying a flexible and adaptive data driven model which can be used in intelligent buildings to reduce the energy demands for heating and cooling. In this paper, we propose a discrete model based on Hidden Markov Models (HMMs).

This paper presents a new Flexible General Branch Model (FGBM) for the power flow solution of hybrid AC/DC grids. The model is an improvement of MATPOWER's original branch model, by incorporating extra degrees of freedom in form of additional state variables to model both conventional AC branches as well as different types of AC/DC interface devices such as Voltage Source Converters (VSC). A detailed description of the proposed flexible model is shown. Furthermore, the model is used in a new unified power flow algorithm based on the Newton Raphson method. This algorithm is also an extension of the already powerful one employed in MATPOWER. Due to the nature of the developed model, there is no need of identifying or differentiate between AC, DC or even VSC nodes. As a result, all power flow calculations are obtained with the traditional NR method. Power and Voltage Control variables are created for all the modelled elements that requires them. Necessary modifications to the original MATPOWER's power flow algorithm to include them are developed and described. Finally, detailed simulations validate the algorithm and model's accuracy.
