Full textElectricity evokes the Greek legend of King Midas, who turned everything he touched into “gold”. Since its artificial creation, electricity has been turning the conditions of human existence to “gold”, by fostering progress through people's comfort or its promotion improving, and through productive activities boosting. From this point of view, it gives access to the effective enjoyment of fundamental rights, because of its impact on food, education, health, drinking water and sanitation, work, etc. This importance justifies the legal basis, especially constitutional, that the Republic of Niger has given to its development. To achieve the objectives of energy sovereignty and universal access to energy, a firm political will on the part of public authorities, and the support of technical and financial partners, are required. However, it requires just as much, if not more, expansion of electricity as a single form of energy. This need for expansion focuses thought on conditions and means; it tests the exercise of powers and rights. This African thesis for Africans is based on a living law approach, one that reintegrates law into its environment, blending numerous legal disciplines (and even non-legal disciplines such as economics and politics). The author argues that the legal framework for the expansion of electricity as a condition for economic and social development is rich, but nevertheless perfectible. He highlights two complementary aspects. Firstly, he observes that the State's sovereign responsibilities are preserved in determining energy options and controlling the electricity sub-sector. Secondly, he shows that the Republic of Niger has chosen to promote private initiative within the framework of public service and individual autonomy

Full textThis dissertation provides a novel wide-area control strategy for damping of critical frequency oscillations via modulation of fast active power injections, which paves the way for the utilization of large-scale geographically dispersed actuators, e.g., distributed energy resources (DERs), in the control of power system low-frequency rotor angle dynamics, this includes the inter-area oscillations and the transient frequency swing. The proposed method incorporates these two different dynamics into a linear time invariant (LTI) system based control framework, in which the control of the transient frequency swing is translated into the control of the system common mode dynamics. For this purpose, a careful examination of the relationship between the transient frequency swing and the common mode dynamics is carried out; extensive simulations show that the common mode defines the shape of a small-signal transient frequency swing. The proposed control method pursues an efficient utilization of the limited power reserve of existing DERs to mitigate these oscillations. This is accomplished by decoupling the damping control actions at different sites using the oscillation signals of the concerned mode as the power commands. A theoretical basis for this decoupled modulating control is provided. Technically, the desired sole modal oscillation signals are filtered out by linearly combining the system-wide frequencies, which is determined by the linear quadratic regulator based sparsity-promoting (LQRSP) technique. With the proposed strategy, the modulation of each active power injection can be effectively engineered considering the response limit and steady-state output capability of the supporting device. In the proposed control framework, the power command signal for the primary frequency control is determined in a (near) optimal control sense; experiments show that this signal tends to be the system speed seen by the power injection point. Importantly, the decoupled modulating control tends to isolate the control actions for the inter-area oscillations and the transient frequency swing, thereby greatly relieving the concern about the interaction between the control of these two types of dynamics.

Full textPower systems are nowadays facing new challenges with the electricity market deregulation, the introduction of distributed generation and the global consumption growth. Consequently, power grids will undergo more stresses and electrical loads will support the system. Thus, load control is considered to take part into networks management and services delivery. The research described in this thesis aims to introduce some load control capabilities in this aforementioned changing context. The contribution of residential thermal loads and household appliances into the management of incidents consequences are considered. Studies enable us to conclude that these kinds of loads have notable abilities for preventive and real time control. The results obtained and the innovation of this research subject, allow us to consider future studies such as, widening works including other type of loads to control and other services to deliver

Full textDue to deregulation in the power sectors of transmission and distribution, Power Quality (PQ) has become a distinguishing feature of electricity, to be treated as a commodity in the open market economy. On the other hand, the proliferation of power electronic equipment has lead to a significant increase of power quality problems. One of the major issues in improving power quality in distribution networks is the mitigation of network voltage distortions for proper operation of industrial process where there are sensitive and critical loads. The first to treat the voltage perturbations such as voltage dips, harmonics, flickers and voltage imbalances, the “dynamic voltage restorers” (DVR), based on the series active power filtering (SAPF) topology, is studied, analysed and discussed in detail in this thesis. Parallel active power filtering (PAPF); as a powerful tool for current harmonics and fundamental reactive power compensation; and their ontrol strategies are also studied. Different aspects concerning PAPF and SAPF, such as voltage and current distortion extraction, voltage source power converters and control strategies and design considerations are dealt with detail. To complete the studies a power flow study is presented to determine the power rating in different parts of a unified power quality conditioner (UPQC) during the faults, which are carried out in a flicker phenomena as an interesting case study. A novel analogical method of perturbation detection is proposed for active filtering, and to stay analogue, the analogue PID controllers are proposed for different parts of a complete UPQC system. Extensive computer simulation using MATLAB/SIMULINK Power System Blockset and experimental results are used to show the viability and performance of the proposed DVR, PAPF and UPQC for different voltage and current perturbations rejection in different conditions both in steady state and transient times

Full textIn this thesis we address the problem of dimensionning metropolitan all-optical rings with low energy consumption. A new architecture for all-optical nodes, called Packet Optical Add-Drop Multiplexer (POADM), improves the performance of metropolitan networks while reducing their energy consumption and therefore their operating costs. A POADM is composed of advanced optical receivers whose unit cost is elevated. The number of these equipments is variable in each node and it determines the performance but also the capital expenditure of the network. We offer design solutions to both ensure network performance while minimizing the cost of deploying it

Full textOur thesis begins by an overview of the optimal coordination of overcurrent relays and distance relays. For an optimal coordination, the relays settings, being the time multiplier setting TMS, the pickup currents Ip and the operating time of the second zone of distance relay tz2, must be determined with the help of linear or nonlinear optimization methods. The objective of the overview is to identify the advantages and the drawbacks of the available methods. The principal disadvantages of the existing methods are no-optimal selection of pickup currents with linear optimization, then the complexity of nonlinear discrete optimization and finally the determination of no discrete settings of relays. Ln order to overcome these disadvantages, we have developed a new method for the optimal coordination of protective relays. The proposed method uses a linear formulation of the coordination problem in order to optimize the relay settings with values complying with setting ranges. The comparison with certain existing methods certifies the efficiency of the proposed method
