This work presents a back to back converter topology with the ability to connect two power systems of different voltages and frequencies for the exchange of power. By utilizing indirect AC to AC conversion decoupling is achieved between the power systems with one of three phase, two level voltage source converters performing the AC to DC conversion that maintains the required DC bus voltage level at unity power factor while the other converter operates in all four quadrants supplying and or consuming active and or reactive power with the other power system. The prototype implementation resides at University of Wisconsin Milwaukee's USR building microgrid test bed facility with an emphasis in the design to approach the requirements for harmonic control as recommended by IEEE 519 without power filtering AC capacitors.

This paper presents an investigation on the comparison between the Maximum Torque Per Ampere (MTPA) and the Field Orientation Control (FOC) algorithms for interior permanent magnet synchronous machines (IPMSMs). In particular, this study was carried out on a small-power IPMSM with low salience ratio. Both control algorithms have been implemented in the Matlab/Simulink environment, obtaining promising results.

This paper evaluates the impact of local government capital investment subsidies for the installation and the price of rooftop solar photovoltaic (PV) system in Japan. By creating the micro-level unique panel dataset covering the period between 2009 and 2014, we compared municipalities that employed subsidies with municipalities that did not to analyze their effects on the amount of installation and the system prices. Our results indicated that the municipal subsidies significantly induced the installation of rooftop PV although their effects depended on the several conditions such as income. On the other hand, we found no evidence of an effect on rooftop PV's system price reduction in municipalities with higher exposure to the subsidies. Subsidies rather seemed to have an effect to raise prices up.

Solar-to-hydrogen energy conversion is a promising technology because it enables high-capacity, long-term storage of solar energy. We propose a new highly efficient solar-to-hydrogen conversion system consisting of multiple converter-electrolyzer sets connected in parallel to a photovoltaic (PV) array. This system is flexible to apply to various PV configurations. One-day simulations based on measured PV and electrolyzer characteristics demonstrate very high maximum power point tracking (MPPT) efficiency (higher than 99.9%) and average power conversion efficiency (94.0%) on a clear sunny day. Annual energy production is expected to increase by 8.5%-point compared with a single converter system using one of the best commercial converter. The key elements of the high efficiency are the new system topology, a specially designed phase-shift full-bridge converter and a control method “P&O with converter scoring” algorithm.

This paper presents an inductively coupled power transfer (ICPT) system that can transfer energy with high efficient from primary side to secondary side with variable load from 50 to 300 Ω via electromagnetic resonant coupling and output stable voltage. Main reasons for low efficiency for wide frequency deviation have been investigated. Typical compensation structures are compared in terms of efficiency, and load range. The series-parallel compensation framework is adopted to keep both side coils work in resonant condition and output maximum voltage. A practical ICPT prototype was conducted and the performance with different compensation networks were compared experimentally. Simulation and experimental results are illustrated to show the stability and effectiveness of this inductively coupled transfer system.

The search for energy alternatives of renewable origin and the reduction of greenhouse gases from the decomposition of waste from slaughter of the camels and the burning of cattle manure have made the present work to be carried out with the objective of obtaining biogas In batch under anaerobic conditions from the mixture of cattle manure with slaughter residues from the Carnal of Pedegral-Arequipa-Peru. Three mixtures of substrates were used: one Ml consisting of 80% cattle manure, 20% bovine and water rumen and two M2 for 20% cattle manure, 30% bovine ruminai content, 50% of blood from cattle and water and three M3 for 10% of beef manure, 20% of ruminai bovine content, 70% of bovine blood and water. These were subjected to different hydraulic retention times (2, 4 and 6 days) and mesophilic TM temperatures (39, 45 and 50°C), resulting in the highest biogas production of 507.0965 ml of biogas/kg of mixture with M3 at a TRH of 6 days and at a TM of 39°C explainable by the high content of N that stabilizes the pH and the isobutyric and valeric acids that increase the biogas production, existing in blood and ruminai content respectively.

Many problems in the electricity demand of grid caused by the increases in the population. Moreover, the use of the conventional sources does not meet consumer demand. In this case, the use of renewable power will be very economical and beneficial to provide the required energy of consumers. In addition to that, smart grid is supposed to improve the quality and safety of renewable energy system through the ICT by providing monitoring and controlling capabilities. In this study, renewable energy potential of Algeria is discussed. Furthermore, a simulation of simple scaled micro grid to show the behavior of its components are performed in MATLAB/Simulink as a simple example of smart grid application.

Management of Renewable Static Synchronous Generation units based on Synchronous Power Controller (RSSG-SPC), not only provides grid synchronization without using PLL and gives proper dynamic to output active power, moreover yields simple solution to overcome technical constraints on these units. Control of active power level injected to the grid is one of these key constraints which can overcome by an Active Power Limiter (APL). In this work, an APL designed based on the classic power equation is proposed for this kind of modern RSSG-SPCs. Primary Simulink analysis and real time test results confirm that suggested APL can control and limit both maximum and minimum level of output active power for several grid connection cases.
