This paper gives a definition of collective self-consumption and introduces the current regulatory framework in some European countries. It proposes a review of relevant Demand Side Management (DSM) methods applicable to improve the collective self-consumption rate. It also introduces the concept of blockchain and its possible applications to collective self-consumption, with a focus on some current experimentations. Current blockchain applications include validation of measured data and energy transactions. New architectures propose a completely decentralized energy market and grid control based on the blockchain technology. However, a deeper analysis of the benefit of blockchain is required. The legal framework will also play a role on the future deployment of these applications.

Maximum power point trackers are so important in photovoltaic systems to improve their overall efficiency. This paper presents a photovoltaic system with maximum power point tracking facility. An intelligent Sliding mode controller method is proposed in this paper to achieve the maximum power point tracking of PV modules. The system consists of a photovoltaic solar module connected to a DC-DC boost converter. The system is modeled using MATLAB/SIMULINK. The system has been experienced under disturbance in the photovoltaic loads and irradiation levels. The simulation results show that the proposed maximum power tracker tracks the maximum power accurately and successfully in all tested conditions. The MPPT system is then experimentally implemented. DSPACE is used in the implementation of the MPPT hardware setup for real-time control. Data acquisition and system control are implemented using dSPACE 1104 software and digital signal processor card. The experimental results show the efficiency of the proposed algorithm and confirm the simulation results.

The water flow rate control, which is the principal control loop required to operate stationary solar fields, can be as simple as designing a PID controller for a unique pump whose behavior can be approximated by a first-order system with delay. Nevertheless, when the water flow rate is manipulated with multiple actuators (pumps or valves), the problem presents some challenges due to hydraulic interactions. This paper presents a multivariable controller scheme to deal with the control of a solar field with five pumping systems. Simulation and experimental results are included to demonstrate the effectiveness of the proposed controller.

Lithium-ion batteries play an important role as energy storage systems in automotive applications like hybrid electric vehicles. For an efficient use in such applications, accurate practical electro-thermal circuit and battery models for Lithium-ion cells are proposed in this paper. The main objective of this paper is to present a model, which can be used in the design process of battery packs, starting with the simulation of battery behavior to the point of model-based energy management controllers and cooling strategies. First, an accurate, intuitive, and comprehensive electrical model has been proposed to capture the entire dynamic characteristics of a battery, from nonlinear open-circuit voltage, current, temperature, SOC and storage time-dependent capacity to transient response. Next, the thermal model is used to estimate the heat generation inside the battery. Parameter estimation for both parts of the model is done separately in a two-stage algorithm by fitting the model output to experimental data. Finally, the coupled electro-thermal model is validated using experimental data. The experimental results show the effectiveness of models proposed.

The problem of fault detection and estimation in electric servo actuators of manipulation robots to achieve fault accommodation is considered. It’s supposed that electric servo actuators are described by nonlinear models with non-smooth nonlinearities. Fault detection problem is solved with help of logical-dynamic approach, which makes it possible to apply linear methods in diagnosing of nonlinear objects. To accurately estimate the real-time values of the appearing faults, it is suggested to add a special feedback by the residual signal in received observers that ensures the observer’s work in a sliding mode.

In this work, the Quantitative Feedback Theory (QFT) method is used to find a control solution for the well-known ACC benchmark problem. Unlike previous contributions, this one addresses the tracking problem. The solution is based on a two-degree-of-freedom control scheme. To cope with the demanding requirements of the problem, an innovative use of Bessel filters as tolerances is presented, replacing the usual second order models.

In this paper, a modified direct feedback linearization method for transient stability and voltage regulation of power systems is discussed. Starting with the classical direct feedback linearization technique currently applied to power systems, a modification is proposed in the equation of excitation control of synchronous generators in order to eliminate the static error of the terminal generator voltage. This modification takes into account the change of the reactance line after a three-phase short circuit. The proposed method is based on a standard third-order model of a synchronous generator which requires only information about the physical available measurements of angular speed, active electric power and generator terminal voltage. Simulation results show that this technique presents a fast response and a robustness compared with the Power System Stabilizer (PSS) and the Direct Feedback Linearization (DFL). They also demonstrate that the damping, the steady-state and the transient stability as well as voltage regulation are all achieved satisfactorily.

This paper is concerned with a backstepping torque control of five Phase Permanent Magnet Synchronous Machine (5P-PMSM). A non-sinusoidal EMF is considered. The design procedure of the control scheme is discussed. Indeed, the objective of the proposed backstepping controller is the minimization of electromagnetic torque ripples due to the non sinusoidal EMF, and also the minimization of the copper losses. Simulation results show the effectiveness of our design, with good transient performances and an excellent torque ripples reduction.

In this paper, a velocity control system for industrial overhead cranes based on a Model Predictive Control approach is proposed. The problem of the control of the operator-in-the-loop system is addressed, as the operator drives the system pushing a button while the control algorithm drives the cart reducing the oscillations of the load. An inner velocity control loop is used in order to overcome some of the problems of controlling the system by using directly the torque of the motor as a control variable. Simulations show the effectiveness of the approach, in particular in the presence of friction.

This paper proposes a new T-S fuzzy method to deal with the power tracking problem of the power generating systems. First, a dynamic model of the PV system is developed which is subsequently converted into a Takagi-Sugeno (TS) model. Then, after leading to this exact model, a fuzzy controller is designed to obtain the MPP even during the variation of the climatic conditions. Based on the T–S fuzzy model, the fuzzy maximum power point tracking controller is designed by constructing fuzzy gain state feedback controller and an optimal reference model for the optimal PV output voltage, which corresponds actually to maximum power point (MPP).The controller gains are obtained by solving a set of linear matrix inequalities (LMIs). Finally, simulation results are given to illustrate the optimal tracking performance of the proposed fuzzy controller even in the case of abrupt changing climatic conditions.
