A proposed parallel power converter with interleaving algorithm is chosen to boost a low dc voltage of photovoltaic (PV) to a dc bus utility level and then follows by inverter. Converters are controlled by interleaved switching signals, which have the same switching frequency and the same phase shift. By virtue of paralleling the converters, the input current can be shared among the cells or phases, so that high reliability and efficiency in power electronic systems can be obtained. In this paper, a nonlinear-control algorithm based on the flatness property of the system is proposed. Flatness provides a convenient framework for meeting a number of performance specifications on the power converter. To validate the proposed method, a prototype PV power converter (1.2-kW two-phase boost converters in parallel) is realized in the laboratory. The proposed control law based on the flatness property is implemented by digital estimation in a dSPACE 1104 controller card. Experimental results in the laboratory corroborate the excellent control scheme.

India's power sector is still highly dependent on fossil fuels. As the energy demand in India is steadily increasing, the government is supporting new and innovative methods in renewable energy to tackle the growing energy deficit and to reduce the dependence on fossil fuels. Decentralized renewable energy systems are particularly important in India because of the distribution, logistics and grid connectivity issues existing in the country. This gives a good opportunity for international renewable energy companies to establish business operations in India. But value networks of decentralized renewable energy systems in the Base of Pyramid (BoP) markets are complex. Traditional engineering perspective suggests companies to understand their own skills related to business and technology before entering a new market. This paper describes a case study in which integrative and collaborative design methods were used during the initial phases of development of decentralized renewable energy systems (DRES) in India. The case study aims at identifying the contribution of design methods in these early phases. Results indicate that design methods visualize a holistic picture of the current renewable energy systems, its actor and the future possibilities in India.

The ongoing trend to sustainable energy supply based on renewable energies is coming along with new challenges in network control. Especially in the low voltage distribution networks, new control structures are required, since they have been considered as a passive system in regards of network control. As a feasible solution for structuring power networks the Clustering Power System Approach (CPSA) has been introduced, in order to allow adequate control architecture. This paper focuses on a new network control application for clustered power systems, being suitable for directed manipulation of power flows in low voltage networks. The core component is a smart inverter system in combination with a battery storage, which will be placed into the connection lines between interacting clusters. The network control application is introduced in this paper and initial results of the capabilities of the smart inverter system, especially at asymmetrical grid conditions, are presented.

This paper presents an experimental study on the efficiency variation occurring in an IPMSM (Interior Permanent Magnet Synchronous Motor) with respect to the direct axis current component and for several working conditions. Such investigation is the starting point for the arrangement of a speed control drive system equipped with a real-time power losses minimization algorithm. More in detail, a test bench is set up to carry out the measurements needed for the final power loss identification. The experimental investigation is developed by performing tests at different speed, magnetization and load conditions. From the obtained results, it can be stated that the IPMSM efficiency can be maximized by simply acting on the direct axis current component, without decreasing the dynamic performances of the drive.

The operation of a synchronous generator connected to a dc load by a six-pulse diode bridge is analyzed in this paper. The dc load has in parallel a high electrolytic capacitor to reduce the ripple in the dc voltage: the dc voltage is regulated acting on the field current of the generator. Such a layout is currently used to create a stable and reliable dc-bus for stand-alone dc systems as in electro-diesel locomotives or ships. Due to the presence of bulk capacitors, the dc side can be considered a voltage source rather than a current source, and the ac voltage across the generator as well as the stator current are considerably distorted. By using simulations based on a dynamical model of the generator, the paper shows the most significant operation modes of the system and gives some insight into the power transfer as well the impact of the harmonics for the design of the generator.

This paper presents a fast and accurate approach for the dynamic electrothermal analysis of photovoltaic (PV) plants with a cell-level discretization. A circuit model is developed for the elementary cell, and an equivalent electrical network is automatically built in a preprocessing stage to account for the power-temperature feedback. The PV plant under analysis is represented as an electrical macrocircuit that can be solved with low CPU/memory requirements and without convergence issues by using any SPICE-like simulator. The proposed strategy can be successfully exploited for diagnostic purposes.

This paper proposes a PWM rectifier and torque controller for wind turbine (WT) with permanent magnet synchronous generator (PMSG). The considered rectifier does not need boost inductor whose current is usually controlled to impose the desired torque. To deal with this issue, in this paper initially the PMSG model is developed then a sliding mode observer is described in details aiming to obtain the estimation of the generator speed and torque. Whenever the wind speed is below the nominal value, the estimated turbine rotational speed is used to obtain the optimum torque to maximize the aerodynamics efficiency. Then, by controlling of boost converter it is possible to impose the desired torque. Simulation results demonstrated that the proposed technique can accurately estimate the rotational speed and torque to implemented the MPPT for the wind turbine as well as to limited the power whenever is required.

This paper introduces a simple method to enable the selection of the most appropriate wind turbine for given sites in which the values of the Weibull shape parameter k and scale parameter c are known. T he matching between site and turbine characteristics can be optimized by defining two important parameters: The capacity factor Cf, and the availability factor Af. Published wind data of 10 sites are used to perform site matching with a variety of commercially available wind turbine generators by evaluating the capacity factor, availability factor and annual energy output. T his study argues that the incorporation of the availability factor in the turbine-site matching process will have an added value in terms of lowering the overall electric energy production cost of the system due to the fact that although the energy required by system peaking units will remain the same, the number of start-ups and shutdown may be reduced.

This paper discuss as the dynamics of a SMPS can be investigated by recurrent neural network (RNN) based models with an Hamiltonian formulation and function used for the training, so leading to a novel paradigm that we call RNNHT model. By using the calculated state variables in a boost converter a RNN is trained by considering also the minimization of the energy stored according to a defined cost function. Simulation results show the improvements in the dynamic performance output prediction versus some well assessed boost converter models in the recent literature.

Among those currently proposed in the technical literature, most Energy Management Systems (EMSs) that are based on the formulation and solution of an optimization problem, can be classified in two categories: some of them solve the problem using Dynamic Programming (DP), which is quite computationally expensive in terms of memory occupation; others, in order to solve the problem using Linear Programming (LP) that has a lower computational cost, introduce a simplification, i.e., they consider positive and negative power flows at bidirectional devices separately, instead of considering the net exchanged power. Furthermore, each currently available EMS is only able to achieve one goal at a time, providing advantages either for the end-user or for the grid manager/administrator. Starting from the above considerations, a novel EMS for residential microgrids is proposed in this paper. It exploits the forecasting of PV generation and load demand profiles by means of suitably chosen and trained neural networks. Furthermore, it is based on solving two different optimization problems during two stages of the algorithm, aiming at reconciling end-user and utility needs. Thanks to a suitable mathematical formulation, it manages to solve the optimization problems using Mixed Integer Linear Programming (MILP), instead of DP. A series of simulations is performed to validate the proposed EMS, whose results are presented and discussed.
