During the last years, the CIGRE C1.35 has performed a pioneer quantitative pre-feasibility study for the concept of a global electricity network. The study has explored the economic costs and benefits of interconnecting all continents as one key enabler of a Global Sustainable electricity system.The present paper summarizes the results of this study in which HVDC interconnections play a key role.

The boosting progress of HVDC (High Voltage Direct Current) technology developed for transmission grid applications can be exploited for distribution network needs as well. This has made raise a growing interest on the development of MVDC (Medium Voltage Direct Current) technology. The present paper provides an overview of the ongoing developments related to HVDC (High Voltage Direct Current) and MVDC (Medium Voltage Direct Current) in Italy. Particular attention is paid to HVDC projects and to MVDC studies that have been conducted in the latest years in Italy.

This paper presents a novel approach for the optimal design of the control system for battery energy storage systems adopted in power systems in the framework of the primary frequency control. The challenge issued by the use of batteries for frequency control in modern power systems is related to the need of the repeatedly deep charge and discharge phases. The presence of intermittent loads and generators, in fact, imposes very stressful power profiles to the battery which imply high rate of degradation to its lifetime. Based on the stress model of the battery, the proposed approach aims to design a control system which allows for containing the state of charge time variation within intervals able to match the requirements of frequency profile improvements and lifetime preservation. At this aim, the typical control scheme for batteries adopted for primary frequency control is analyzed and elaborated to address stable dynamic behavior of the regulator. Moreover, starting from the observation of the statistical nature of the power request for the pure frequency regulation service, a statistical study is conducted to perform an optimal design of the regulator in terms of both lifetime duration and primary frequency regulation service.

The paper presents the results of an on-going collaboration between two Italian universities, Politecnico di Bari (PoliBa) and Politecnico di Torino (PoliTo), for the setting up of a permanent cooperative co-simulation platform, that permits to share real-time laboratory resources for both research and education applications. The two laboratories, LabZERO and G-RTSLab, are located at a geographical distance of about 1,000 km. By sharing their lab resources, PoliBa and PoliTo aim to increase number and extent of the possible methodologies, control apparatus and power devices that can be jointly tested, and to develop specific applications of Remote Power-Hardware-in-the-Loop (R-PHIL) co-simulation in the framework of Transmission-Distribution-Customer coordination. Test results are presented to assess delays in remote communication and to estimate how much sample rate and size of data packets affect such delays. An experimental test of the R-PHIL platform is also presented to demonstrate the stability of the proposed co-simulation architecture.

The combination of two sensor less technique for permanent magnet synchronous motor (PMSM), namely Direct Flux Control (DFC) and back electromotive force (BEMF) based technique, is presented within this work. The issue of implementing a complete speed range sensor less control of the electrical machine is addressed. The idea is to use a Kalman filter in order to estimate the entire state of the machine using only the measured currents. The system variables can be observed thanks to the BEMF components. The complete observability of the system state is maintained also at standstill operation by adding the Direct Flux Control signals to the measurements. The aim of this work is to obtain a smooth combination between these two technique in order to robustly control the motor.

The aim of this paper is to develop a control function that is able to manage, in the on-line environment, the active power output of a microturbine so as to compensate the unavoidable microgrid power imbalances caused by forecasting errors and unforeseen events. A central controller based on a Proportional-Integral-Derivative (PID) control loop evaluates the optimal control actions to be sent to the local controller of the microturbine inverter. In order to test the ability of the proposed controller to follow any change in the load demand of the microgrid, experimental tests have been performed on the microturbine connected at the experimental microgrid of the Polytechnic University of Bari, Italy.

In order to ensure power system reliability and security in long term scenario, the identification of the costeffective interconnection levels is one of the main objectives in the modern network planning framework. Terna, the Italian Transmission System Operator (TSO), with the goal of defining the efficient target capacities for each significant market section of the Italian power system developed a novel iterative methodology. The aim to this paper is to provide an exhaustive presentation of the procedure and to show the results obtained for the critical section Centre South–South. In particular, the price spread and the number of congestion hours resulting from market simulations are the main parameters investigated to decide which sections/borders are suitable for additional transmission capacity implementation. The corresponding benefits must be verified by the means of market and network analysis in order to demonstrate the cost-efficiency for the system. The analyses were carried out in two different contrasting future energy scenarios in order to obtain the related different development strategies.

In recent years the social responsibility initiatives have gained a growing role, becoming a focal activity for a large number of commercial and industrial companies. Several of these initiatives are addressed toward the support to the energy needs of the villages where the rural economy is prevailing. The strength and weakness of these activities realized in the field of rural energies are here examined. The study discusses the status of the Research & Development on the matter and takes into account the capability of local energies to support the achievement of the Millennium Development Goals.
