Traditionally, the design of the primary undergrounded circuits for electrical distribution has been based on technical exploitation criteria, as load capacity, reliability, service quality, losses, and economical concerns as installation cost, being so achieved a compromise which minimizes the investment cost on the basis of optimizing the cable section. This procedure maintains its validity from the technical point of view but, nowadays, a new environmental and economical concern should be taken in account in order to determinate the optimum section of an undergrounded cable. This new factor is just the emission of greenhouse effect gasses, as CO2, consequence of the primary source of energy used in the electrical energy production. The ecological impact of these emissions is being increasing its relevance as increases the social conscience on environmental concerns, in particular, since the signature of the Kyoto Agreement. In this work, we present a designing method which considers the part of generation of energy necessary to cover the losses in the undergrounded distribution lines, and includes the cost of the CO2 emissions in the computation of the optimum section of the cable. It is concluded that by increasing the section in such a way, a relevant amount of the Joule losses can be saved in comparison to that produced by the cross section obtained by a classical procedure. The investment excess could be paid back quickly by avoiding administrative fines and by selling the corresponding emission rights.

One of the most important issues on the power system course is the study of the transient power systems. However, due to the complexity of the power systems networks, for an effective instruction of this topic it is required to use a computed simulation environment to provide a complement to analytical methods. Therefore, a methodology for the modeling of power systems on the transient analysis using a MATLAB/Simulink program is proposed. This methodology allows producing voltage and current transients that correspond to fault events, instabilities and the introduction of power electronics equipments in the power systems. Furthermore, this also allows students take advantage of the mathematical models they have derived to perform the desired simulation. Since state space models are used, this simulation tool is useful to study the transient phenomena and easier to compare with power systems laboratory results. So, students can understand how a simulation program have been developed, their capabilities and limitations. Several illustrative examples will be presented in order to clearly show the proposed methodology.

This research paper analyzes the potential impacts of the Plug-in Hybrid Electric Vehicles (PHEV) on the Portuguese electric consumption profile. The plug-in vehicles will affect utility operations by adding additional electricity demand. There has generally been the expectation that the grid will not be greatly affected by the use of these vehicles, because the recharging would only occur during off-peak hours. Several scenarios of PHEVs' penetration are studied considering the grid-for-vehicle (G4V) energy transferring as a primary approach. Depending on the power level, timing, and duration of the PHEV connection to the grid, there could be a wide variety of impacts on grid constraints, capacity needs and emissions generated. In a strong penetration scenario, if many households charge their PHEVs over the same time period, especially if it is when the owners first return home and the domestic consumption is increased, then the peak may be higher than the utility expects. Evaluating the potential impacts that different charging scenarios can have in the demand profile is important so that the distribution utility and regulator understand the problems involved and anticipate ideas that will better optimize the whole system in the future.

The paper presents researches on increasing the efficiency of the photovoltaic conversion by designing a dual-axis tracking system that adjusts the position of the PV module in order to maximize the incident radiation. The design of the tracking system is approached as a mechatronic concept, integrating the control system in the mechanical model of the tracking mechanism. The paper proposes a design strategy based on two steps: designing the optimal tracking system that intends to minimize the actuating forces necessary to track the Sun path, and designing the optimal control law in order to minimize the energy consumption for orientation. The structural solution of the tracking system for study is developed using a method based on the multi-body systems (MBS) theory. The design steps are performed by developing the virtual prototype, which is a control loop composed by the mechanical structure connected with the dynamic model of the actuators and with the controller model.

In recent years the possibility of incorporating type II high temperature superconductors (HTS) into power applications such as electrical motors, generators, bearings and fault current limiters has attracted much attention. Hysteresis superconducting motors offer the simplest construction and in this paper a drum and disc type configuration are considered. Comparison in terms of specific torque produced by both type of machines is presented.

Recent researches in load forecasting are quite often based on the use of neural networks in order to predict a specific variable (maximum demand, active electric power or hourly consumption) using past values of the same variable and other exogenous factors proved to influence the value being predicted. This work aims to explore different input patterns in neural networks incorporating information derived from load profiles of different consumers' classes.

Energy systems are frequently based on imported fossil fuels, and this is a problem in different dimensions including, the environmental, the economic and the security of supply, the latter being particularly relevant for any isolated system, like Islands. Renewable energy is regarded as a solution to this problem, particularly considering its transformation in electricity but this does not include the impact of the transportation sector, which represents a significant component of the imported fuels consumption. The other main limitations associated to renewable electricity consists on the need to increase the storage capacity that might attenuate the effect of renewable energy sources intermittence and disparity between supply and demand. In both these main problems associated with renewable energy management, the Plug-in Electric Vehicles (EV) could be a part of the solution in that the use of the vehicle to grid (V2G) technology can provide storage of electric energy during low demand times and use it to match the demand in peak hours and/or to avoid fossil fuel consumption. However, could the large scale EV penetration lead to increasing the fraction of electricity from renewable? Is the usage of EV batteries like as a storage system truly the best solution? Is the EV a better solution for the vehicle's owner than the internal combustion vehicle from an economical point of view? This paper analyses a case study in the Island of São Miguel in Azores, where energy systems modeling is used to assess how far large scale EV penetration may lead to increasing the potential for the use of renewable electricity, and discusses the possible revenues for EV owners from providing vehicle to grid power.
能源系统经常以进口矿物燃料为基础，这是一个不同方面的问题，包括环境、经济和供应安全，后者对任何孤立的系统，如岛屿，都特别重要。可再生能源被认为是解决这一问题的办法，特别是考虑到它在电力方面的转变，但这并不包括运输部门的影响，运输部门是进口燃料消费的重要组成部分。与可再生电力有关的其他主要限制包括需要增加存储容量，这可能会减弱可再生能源间歇性和供需差距的影响。在与可再生能源管理相关的这两个主要问题中，插电式电动汽车(EV)可以成为解决方案的一部分，因为使用车辆到电网(V2G)技术可以在低需求时期提供电能存储，并使用它来匹配高峰时段的需求和/或避免化石燃料的消耗。然而，电动汽车的大规模普及是否会导致可再生能源电力比例的增加?使用电动汽车电池作为存储系统真的是最好的解决方案吗?从经济的角度来看，电动汽车是否比内燃机汽车更好?本文分析了亚速尔群岛的s o Miguel岛的一个案例研究，在这个案例中，能源系统模型被用来评估大规模电动汽车的普及可能会在多大程度上增加可再生电力的使用潜力，并讨论了电动汽车车主将汽车提供给电网的可能收入。

Modern manufacturing lines are very sensible to power quality disturbances whereas voltage disturbances have been clearly identified as major problems to sophisticated continuous-process-based industries. Topic of power quality is also of crucial importance for the widespread application of renewables and deep penetration of energy sources of distributed power generation. Due to the insufficient ability of batteries to absorb power surges and spikes and to deliver high energy bursts, batteries based uninterruptible power supply systems (UPS) are simply purely suited for short-term bridging by power drop or spike compensation. To handle power surges and short-term power outages the energy market needs supercapacitors with their significant benefits in power- and peak-assist. Supercapacitors are reliable, maintenance-free, short-time power source with long lifespan and are suitable to avoid the effect of voltage twist and of electrical noise or to buffer short-term outages on the power grid. Some fields of application as well as design of supercapacitor based systems have been presented taking into account specific technical requirements on power quality systems.

In the field of poly-phase electric machines, a variety of stator winding alternatives is possible in terms of phase physical arrangements. The specific winding scheme, in addition to the number of phases, needs to be taken into account as far as the machine dynamic modeling is concerned. In particular, the Vector-Space Decomposition (VSD) method, which is widely used for n-phase machine analysis, requires different transformation matrices to be used depending on the displacement angle between successive phases, as discussed in a companion work. The explicit forms of such matrices are illustrated in this paper, taking the VSD of a five-phase motor, for different possible phase arrangements, as a numeric case study and validation example.

A multi-index nonlinear coordinated control scheme for BESS and generator excitation is proposed. The proposed multi-index nonlinear coordinated controller can effectively coordinate the dynamic and steady-state performance of the controlled system. It can enhance the stability of the system, improve the dynamic characteristics of state variables, and can improve the control accuracy of output variables such as terminal voltage, active power output of the generator. Simulation results show that to control BESS and generator coordinately has the advantage of enhancing the stability of the system. With the ability of BESS to control the active power and reactive power, and coordinating generator excitation regulate, the dynamic characteristics of state variables can changes more smoothness, and the responds are more speedily.
