Output System

Renewable energy is needed as an alternative energy source. One of the implementations of renewable energy is the Solar Power Plant (PLTS). PLTS is a component that uses solar cells to convert solar energy into electrical energy. Unfortunately, the output power of this solar cell depends on the intensity of the light which causes the output power to enter the load to be unstable. Sometimes the PV power decrease because of the shading effect. From this problem a converter is needed to keep the system output voltage. The converter used in this research is the zeta converter. This Zeta converter can operate like a buck boost converter. The output of the system used is not stable. So that to stabilize it requires good control. In this paper using PI controller to control this system in order to keep the output system stable. 3. The error generated using the PI Control on the system is only 0.34%.

In recent years, several factors such as environmental pollution which is caused by fossil fuels and various diseases caused by them from one hand and concerns about the dwindling fossil fuels and price fluctuation of the products and resulting effects of these fluctuations in the economy from other hand has led most countries to seek alternative energy sources for fossil fuel supplies. Such a way that in 2006, about 18% of the consumed energy of the world is obtained through renewable energies. Iran is among the countries that are geographically located in hot and dry areas and has the most sun exposure in different months of the year. Except in the coasts of Caspian Sea, the percentage of sunny days throughout the year is between 63 to 98 percent in Iran. On the other hand, there are dispersed and remote areas and loads far from national grid which is impossible to provide electrical energy for them through transmission from national grid, therefore, for such cases the renewable energy technologies could be used to solve the problem and provide the energy. In this paper, technical and economic feasibility for the use of renewable energies for independent systems of the grid for a dispersed load in the area on the outskirts of Isfahan (Sepahan) with the maximum energy consumption of 3Kwh in a day is studied and presented. In addition, the HOMER simulation software is used as the optimization tool.

Biogas Energy

Processing of agricultural and livestock waste produces biogas which is then used by the community to substitute natural gas energy and substitute electricity for clean water supply and produce organic fertilizer for farming purposes. This research was conducted using descriptive methods, by describing how to treat agricultural and livestock waste. Then a quantitative approach is used which aims to describe or explain the conversion of biogas energy into electrical energy. Biogas has good prospects as an alternative energy substitute for non-renewable energy in Indonesia which is experiencing an energy crisis which is characterized by increasingly scarce and high fuel prices which have an impact on the higher costs of generating electricity. In the Ganjar Farmers-Farm Group, the use of biogas by using goat / sheep dung is very potential, from 300 goats / sheep has the potential to produce electrical energy of 32.4 kWh / day. Most of the power plants that supply the Pati Regency region still use energy sources made from non-renewable energy materials. The depletion of fuel for these non-renewable plants, power plants with renewable fuels are absolutely necessary.

Electric energy is an important factor for human needs, functions as lighting, and various human activities. The large amount of electrical energy needs demands to create various alternative electrical energy. Alternative energy uses renewable energy sources to avoid crisis and energy scarcity. The National Energy Policy (KEN) has encouraged the government and the private sector and the public to use energy effectively and efficiently, and to utilize renewable energy. The direction of national energy policy includes reducing dependence on fossil fuels, specifically petroleum. Utilization of renewable energy is needed for the sustainability of national energy supply and reserves. Indonesia is called a maritime country, because 2/3 of Indonesia’s territory is the sea with the longest coastline in the world, which is ± 80,791. 42 Km and is also called an archipelagic country because it has thousands of islands. This natural situation is a great potential for the development of renewable energy, especially the energy sourced from the sea spread wide and very abundant, namely solar pond. One of the alternative sources of renewable energy sourced from the sea currently not developed in Indonesia is solar ponds, even though Indonesia has a huge geographical potential to develop this technology. There are at least two potential parameters for building a solar pond, first because Indonesia has a tropical climate with a large enough intensity of sun, second because Indonesia is a maritime country surrounded by sea, so the availability of raw water is very abundant. Solar pond is not a new power generation technology. In the history of electricity generation technology in Indonesia, this technology has never been tested and implemented at all. In this study, it has a long-term goal of generating electricity from solar ponds. Solar pond technology is a type of environmentally friendly power plant, based on seawater using sunlight to get the difference in heat in the solar pool so that the thermal layer can be converted into electrical energy. The specific targets, namely data salinity and temperature data on the prototype solar pond have been realized in the form of cylindrical with a height of 1. 05m and a diameter of 0. 8 meters. Solar pool research, in line with the goal of national transformation as a significant contributor to the benefit of the Indonesian Maritime Continent. In line with the development of electricity generation technology, solar pond technology has never been implemented in Indonesia, so this research is in accordance with the 2016-2020 National Strategic Plan number 51868 / UN4. 1 / PR. 04 / 2016.

Energy independence was chosen by Ukraine as one of its development priorities; it covers the reduction of gas consumption and the gas replacement, increase of the energy efficiency in various public life spheres, development of the renewable energy sector. Many published papers of Ukrainian scientists, as well as expert’s reports are dedicated to the challenges in the rollout of the renewable energy sector, however the regulatory and legal support for the development of the aforementioned sector has been considered only fragmentary. Therefore, the issue of the legislative control of the renewable energy sector development under the current European integration conditions requires further research and systematization. Purpose of the article is to determine the major contradictions reflecting the current status of the regulatory and legal control in the renewable energy sector development, to research and propose the corresponding improvement prospects. The article is presenting the regulatory basis assessment and systematization of the Ukrainian renewable energy sector legislation. Insights are given to major contradictions observed in the regulatory and legal provisions of the governmental regulation related to the renewable energy development. Practical proposals are made for the improvement of the legislation related to the provisioning of the Ukrainian United Energy Power System operational safety during the peak-load hours through introduction of the electrical energy storage system. Over the past years, Ukrainian authorities have made several important efforts towards the creation and development of the legislative basis in the renewable energy sector, however this sector is still considered in the context of the alternative energy development, which becomes a prospect for further investigations.
