Renewables and Efficiency

The new formulation for the electrical modeling of the three-level converter combined with the new control strategy reveals the capability in mitigating the unbalancing between the capacitors bank voltages. The THD of the output current with the two-level converter and with the three-level converter have propensity to be decremented with …

The creation of a flexible. efficient. digitized. dependable and resilient power grid may well be the best route to increasing energy efficiency &amp. security. as well as boosting the potential of renewable &amp. distributed power sources. This book covers smart grids from A-Z. providing a complete treatment of the topic. …

This paper presents Genetic Algorithm based reconfiguration scheme for the arrangement of PV modules in a PV array which exhibits increased array power generation under partially shaded conditions. The reconfiguration technique involves changes in the electrical interconnections for shade dispersion keeping the physical location of the PV modules unchanged. The …

In this paper. a modeling method based on the genetic algorithm is proposed. The values of the PV module parameters were computed in such a way that the error between the simulation results and the data sheet information is minimized. A global optimization for the values of the parameters was …

This book provides a unique multi- and interdisciplinary approach to energy conversion technologies by shedding light on the topic from both technological and ethical perspectives. It applies these concepts to examples of engineering problems related to energy conversion – an internal combustion engine and a fuel cell – in order …

In this paper. a novel type of CPC-SAC is presented. A series of experiments was conducted in 2014 in Beijing. China to investigate the thermal performance of the novel SAC. The collector exhibited a stable performance during the test period. with an annual average thermal efficiency of 52%. The novel …

Based on the proposed technique. a two stage power electronic system architecture has been proposed as shown in Fig. 5. The system comprises of a boost type dc–dc converter and an inverter to feed the power generated by PV array to the grid and grid connected loads. The system configuration …

The goal of this study was to detect barriers to and opportunities for promoting nearly zero-energy dwellings on the basis of end-user experiences. by studying end-user satisfaction with nearly zero-energy houses. Developments in Germany and Austria (mainly the building of passive houses) are related to the European requirement for the …

For all we know today. and for all we can learn from history. the convergence of national energy intensity levels at lower and lower global values should continue—as long as economic openness allows global fuel trade. the exchange of technical knowledge and the standardisation of products to continue. Likewise. fuel …

Conventional architectures of the renewable energy based Hybrid Power Systems are majorly associated with power quality issues as discussed in Section II. This is the primary concern which leads for the novelty in this paper. The paper is focused on the design of renewable energy based HPS with power quality …
