Renewable Energy Generation

Electrical energy crisis related to the increasing population in an area will increase the electrical energy customers. Besides diminishing reserves of fossil energy that is required of alternative energy from renewable energy sources. The problem is in incorporating a potential source of renewable energy with a generator needs power generation hybrid, the hybrid system with a generator as backup energy utilization is less than optimal because when there was a deficit power generator takes over all of the power wasted in renewable energy generation. The purpose of study is to produce a hybrid system design between the generation of solar energy, wind energy and generator as support (support) when the power deficit in energy of renewable generator. Research Method in the design of hybrid system is a design block diagram consisting of solar panels, wind turbines, inverters, and generator. At this stage it has produced research outputs in the form of models of hybrid renewable energy generation systems and generators, then make a circuit simulation and measurement. The results of this research is a hybrid system that works adaptive- connected the generator to the system when the power deficit or increase the load to provide power support on renewable energy generation. This hybrid system with a capacity of 3.5 kW less power than the previous system with the composition generator 5.7 kW 2.2 kW of renewable energy consists of a 1 kW solar panels, wind turbines 1.3 kW and 1.3 kW generator voltage at 310V DC bus coupling, the voltage on the bus coupling AC 220V / 50 Hz, total load current at 16A. The percentage utilization of renewable energy rose from 11.73% to 24,94% and generator utilization fell from 24.50% to 16.74%.

Renewable energy generated from sunlight (Solar Panels) can be formed as alternative energy that can be applied to a source of electrical energy in rice thresher equipment. The use of solar energy with a power of 240 WP through the object on the rice thresher is able to replace the rice thresher automatically which is more effective. The power generated by solar energy will be processed into a charging source for the Regulated Battery Charger which can be supplied at a voltage to the control circuit to drive the DC motor. The average voltage generated by solar energy is 0.000394 volts/lux with a maximum voltage of 36.2 volts and a DC motor of 350 watts. In addition, the speed of this rice thresher is 950.8 rpm and is able to produce very good rice cutting against the designed solar energy capabilities.

Renewable Energy Generation

Decarbonisation is becoming a central aim of countries around the globe, ensuring the effects of climate change do not increase exponentially in the coming years. Renewable energy generation is at the core of this decarbonisation process, enabling economies to divorce themselves from a reliance on oil and coal. Hybrid energy systems can utilise multiple generation methods to supply electrical demand best. This paper investigates the use of localised hybrid energy systems around the UK, comparing the financial viability of solar, wind and hydrokinetic generation methods both as a hybrid system and individually in different scenarios. The significance of having localised hybrid energy systems is that they address two large problems within renewable energy generation, that of storage issues and also generating the electricity far away from where it is actually used, requiring extensive infrastructure. The microgrid optimisation software HOMER was used to simulate each of the generation methods alongside the national grid, including lithium ion batteries and converters to create a comprehensive hybrid system. Net Present Cost, which is the current value of all the costs of installing and operating the system over the project lifetime, was considered as the metric. The analysis finds that for each modelled location, wind turbines in combination with lithium ion batteries and a converter is the system with the lowest Net Present Cost, with the exception of Bristol, which also uses hydrokinetic turbines within the system. The findings indicate the extensive wind resources available within the UK, along with identifying that certain locations around the country also have very high potential for tidal power generation.
