Abstract

The present invention relates to a method for the autonomous control of the operation of medium-range energy storage systems for electrical energy distribution systems. This method aims to mitigate more significantly the technical impacts of the introduction of emergent technologies, such as photovoltaic generators, and is divided into two techniques. The first technique, called movement of the operating thresholds, aims to reduce the peak demand and improve the load factor upstream of the site of installation. The second technique, called voltage variation using the capacitance of the inverter, improves the voltage profile downstream of the site of installation, which essentially allows increased penetration of microgeneration throughout the network. The main advantage of the method is generated by the autonomous adjustment of the parameters of both techniques according to the site of installation, which simply requires local measurements for operation of the storage system. This means that it is not necessary to invest in infrastructure for data collection or to anticipate energy demand/generation along the network in order to execute the proposed method.

Abstract

The present invention relates to a method for producing bioethanol from banana pseudostem by enzymatic hydrolysis, using a pre-treatment with sodium hydroxide pure or in combination with sodium hypochlorite, acetic acid and/or vinegar in combination with hydrogen peroxide, sulphuric acid, the combination of sodium hydroxide and sulphuric acid, the combination of vapour explosion and sodium hydroxide, followed by enzymatic hydrolysis of the biomass pre-treated with the NS 22074 and NS 50012 cellulase enzymes in an ultra-sound bath or shaker-type bath, the best result being obtained by enzymatic hydrolysis of the biomass in a shaker for 48 hours, with 3% sodium hydroxide (0.2 g), a mixture of the NS 22074 enzyme (0.015 mL) and NS 50012 enzyme (0.015 mL), since only 1.2 kg of pre-treated biomass and only 180 mL of the mixture of the NS 22074 and NS 50012 enzymes are required to produce 1 kg of fermentable sugars, thus proving to be an economically viable method for producing bioethanol.
