The simple principle of wind power plant is use wind as main exciter to rotate the turbine. The turbine convert wind to electric energy. The output signal is alternating (AC) current. This current was changed to direct current (DC) by rectifier circuit. The DC current was used as charge the energy storage, battery. Next step, the DC current from battery convert to AC current using inverter circuit. The result of inverter shows that the error is 20% with 240V no load.

The self-consumption without surplus to the grid is one of the aspects of the new Spanish law for prosumers. Increasing the share of renewable energy sources into the grid inherently leads to several constraints. The mismatch between the energy demand and the renewable energy production, which is intermittent in nature, is one of those challenges. Storage offers the possibility to decouple demand and supply, and therefore, it adds flexibility to the electric system. This research evaluates expanding electricity self-consumption without surplus to the grid by harnessing thermal mass storage in the residential sector. The methodology is investigated by using a variable refrigerant flow air conditioner system. Because there is no option to export the excess capacity to the grid, this research proposes an approach to profiting from this surplus energy by activating structural thermal mass, which is quantified from the information acquired using a building energy model. For this purpose, an EnergyPlus model of a flat in Pamplona (Spain) was used. The optimization analysis was based on a set-point modulation control strategy. Results show that under adequate climatological circumstances, the proposed methodology can reduce the total electric energy from the grid between by 60– 80 % .

Photovoltaic energy conversion is an efficient renewable source affordable as a technology even on the household level. Several technological aspects are subject to continuous improvement. This paper tackles the possibilities for denser panel population of a photovoltaic plant thus more efficient space utilization. The objective is to develop a mathematical model of inter-shading among the photovoltaic panels. The model calculates the electrical energy obtained from panels and considers the shading among the panels. The geographical location of the plant location, the distances between the solar panels and their angle of inclination, the dimensions of the panels and the time interval under evaluation are the parameters which are important for placing the power plant. The results show how much electric energy can be obtained from a certain set of photovoltaic panels. The results indicate, what are the distances between the panels for better allocation of resources when deciding on the number of solar panels and their arrangement.

The exploitation of Mechanical Biological Treatment is quite diffused for treating fractions of Non-Differentiated Waste. A large part of the Italian Mechanical Biological Treatment facilities operate mainly by reducing and stabilizing the Non-Differentiated Waste mass before landfilling. This way of managing Mechanical Biological Treatment can be improved by the adopting a new treatment section, based on the Solid State Anaerobic Digestion process. In this way, the Waste Organic Fraction arising from the mechanical sorting of the Non-Differentiated Waste can be treated before the aerobic stabilization section of the existing Mechanical Biological Treatment. In Italy more than 40% of the working Mechanical Biological Treatment facilities have features suitable for being upgraded with a new Solid State Anaerobic Digestion section. In these plants the amount of the rapidly biodegradable fraction is about 1,100,000 tonnes per year, leading to the production of about 300 GWh of renewable energy. The results concerning a real case study show that, with the adoption of a new Solid State Anaerobic Digestion section, about 150 kWh of electric energy would be able to be produced per each tonne of Waste Organic Fraction. Furthermore, there would be a significant reduction in the Organic Load Rate [kgVS/m3*day] for the existing aerobic section of the plant, leading to additional savings of 160-320 kWh per day, depending on the amount of Waste Organic Fraction diverted from the Solid State Anaerobic Digestion. Results from the economic analysis show that the Solid State Anaerobic Digestion treatment cost ranges from about 6 up to 23 € per each tonne of Non-Differentiated Waste entering the existing Mechanical Biological Treatment plant.

One effort to overcome the energy crisis is to utilize wind energy as a power source. Angina power Plant is a method for generating electrical energy by rotating the angina turbine connected with the generator, the electric energy produced by the generator is stored in an element of electric energy storage (battery). The next one will be channeled to load center like household. The Perarancangan of the horizontal type flat Multiblade Sudu is using a microcontroller that can change the angle of the sudu according to the wind speed so as to maximize the power of wind potential energy. For a sudu angle setting that can adjust the speed of the wind, use two servo motors that have been control by the Arduinouno from the input anemometer so that the angle of the sudu can adjust the wind speed. The results have shown that the turbine-angle arrangement of the turbines can increase the rotation of the wind turbine, thereby increasing the voltage raised in the generator. The optimal angle of the Sudu is at a 15o angle, at a wind speed of 9.5 m/s, resulting in a turbine round of 610 rpm.
