Today, global energy consumption is dominated by fossil fuels such as oil, coal and gas. The intensive consumption of these energy sources gives rise to greenhouse gas emissions and therefore an increase in CO2 emissions. Photovoltaic energy has persistently been considered as a green and pollution-free renewable energy source to overcome greenhouse effect and energy crisis. This paper describes a new method of photovoltaic energy sharing in standalone micro-grids using photovoltaic panels. This approach is based on automatic electrical energy sharing depending on the state of charge (SOC) of the electrical storage unit using by each home and on the electrical power consumption of each home.The monitoring system is connected to each home in micro-grid, it manage each home’s energy use, and assigns more energy to a large energy-consuming home. This architecture contributes to reducing total energy lost.

Control And Monitoring System

The increasing demand for electrical energy and the decreasing supply of fossil fuels in recent years have increased the cost of electrical energy. So that the culture of saving electrical energy is a habit that must be cultivated in the community. On the other hand, energy-saving behavior cannot be realized massively without a support system that can control energy use. With these concerns, it is necessary to develop a method that encourages a culture of saving electrical energy. This paper proposes a system that supports active energy efficiency methods that can support an energy-efficient culture. This system is an electric power monitoring system that is integrated with a smart electrical panel that continuously monitors the use of electrical energy and can control electrical loads automatically, record electricity usage, provide comprehensive reports and analyze energy usage. The method used to carry out this research is research and development. This research has produced a prototype of electrical power control and monitoring system that has a smart panel based on a raspberry PI 3 and PZEM-004t power energy meter. The monitoring system performs and executes automatic control of electrical loads. The system can also provide reports in the form of data monitoring in daily, weekly, monthly or annual period. From the test results, it can be concluded that the system can work well. This research is expected to contribute to providing a system that can support government efforts in saving energy.

Electric vehicle technology becomes increasingly important as it takes care of the environmental issues related to ICE vehicle and reduces the dependency on fossil fuels. Electric vehicle being greatly dependent on the limited electrical energy provided by a battery, the power flow efficiency is very important in this context. Electric vehicle integration to the distribution grid is increased at a faster rate because it can act as power backup to the grid/local loads reducing the peak load and filling the valley point. Most of software engineers own an Electric Vehicle based on eco-friendly principles. The Batteries in the car are connected to the charging point (or) grid monitoring of State of Charging (SOC) facilities in the parking area of company. When the Renewable power (solar energy) is available, the batteries will be charged to hundred percentage of SOC. Then excess power from PV will connect to load as well as grid. When the electrical power supply cutoff the car batteries will act as a battery bank of UPS and support to the critical load with condition based Allowable SOC. The total capacity of the batteries depends upon the no of cars available at a particular shift in a day. This work proposes the power backup of EV is utilized as an UPS to Software Company as well as used to support the Dynamic Voltage Restorer (DVR) to mitigate the fault occurring in the distribution system. Additionally, the EV supported DVR compensates voltage harmonics, voltage sag-swell, voltage interruptions coming from distribution to enhance power-quality of entire EV system without any additional compensation devices. The entire system is modeled using MATLAB/SIMULINK and the results confer the feasibility of the proposed objective.

The Difference

‘Energy systems’ explains the difference between energy and power and between energy and electrical energy. It then outlines the sources of primary energy, describing the environmental consequences of burning fossil fuels, and attempts at limiting energy use. It also considers the difficulties of storing electricity in large quantities and cost-effectively. It is impossible to conceive of a modern society without reliable and effective systems to provide energy when and where it is needed. Modern energy systems continue to evolve in response to energy demand and to changing sources of supply. Increasingly environmental considerations and costs determine which energy sources are used and how the energy transmission and distribution networks are constructed and operated.

Electrolysis Method

Electrical energy is one of the primer facilities used in every activity. Almost all the existing facilities use electricity. This is inversely proportional to the depleting energy source. The solution to this problem is to replace fossil fuels with renewable energy sources. Renewable energy is a source of energy that can be recycled and does not damage the environment. One type of renewable energy is to use the electrolysis method. Electrolysis Method is one of the renewable energy sources. This method uses electrolyte solution which can be found in sour and runny fruit such as lemon (Citrus Limon L.) and Wuluh Star fruit (Averrhoa bilimbi). The study was conducted in a laboratory by mixing the results of the juice of the two fruits with different compositions. The mixes are placed in the arcs (a mixture container to test the electrical properties) and then tested using a multimeter every 2 hours for 24 hours. The results are described in graphical form. The average power of each mixture is, C1 = 2.2mW, C2 = 4.7mW, and C3 = 8.5 mW and based on the graph, each mixture has decreased voltage and current. Even so among the three mixtures, the third mixture has a better electrical power value than the other two mixes. This shows that the higher the acidity of a solution the higher the electricity produced.

The Impact

Air conditioning in the room functions to regulate humidity, heating and cooling the air in the room. The purpose of this conditioning is to provide comfort for the user. The process of cleaning the condenser and evaporator pipe fins can improve compressor performance. The research was conducted on an air conditioner with a capacity of  1 1/2 PK using refrigerant R-22. With an average mass flow rate of 82.5 kg/s before cleaning and 79.6 kg/s after cleaning, it decreased by 4.4%. This has an impact on refrigeration where the average value of the impact of refrigeration before cleaning is 145.4 kJ/kg and after cleaning is 150.6 kJ/kg. This means that after the cleaning process, the evaporator can increase the refrigeration in the air conditioning system by 3.4%. The parameters used are the consumption of electrical power, the temperature of the refrigerant entering and leaving the condenser, the temperature of the refrigerant entering and leaving the evaporator. The increase in compressor performance after the cleaning process is carried out, it can be seen from the total value of electrical energy use before cleaning is 10.9 kWh, and after cleaning it becomes 8.8 kWh. This has an effect on the consumption of electrical energy to drive the compressor to be more efficient by 19.26%. COP an average of 3.6 before cleaning and after cleaning to 4.9 means an increase in compressor work by 1.3 or by 26.5%. Compressor work has decreased by 4440.4 Watts or a decrease of 26.8%.
