The electricity need in the G4 Building at the State University ofMalang was more than 85 kVA. All electrical devices could beactivated; but when the energy source was inactive, all electricityrequirements were transferred to the diesel power plant (DPP).However, the electrical capacity of DPP was only 20 kVA;therefore, it was necessary to optimize the electrical power load sothat the DPP energy could be absorbed optimally using the roomscheduling and electrical devices priority systems. The DynamicProgramming Algorithm was embedded in the power optimizationsystem to help optimize the work. The power optimization prototypewas used to simulate the 1st floor of the G4 Building’s condition.The system consisted of a controller, a central controller, and auser interface. the controller comprised of a current sensor,microcontroller, and a relay. The central controller consisted ofRaspberry Pi 3 hardware that was installed as the server to answerthe HTTP request from the controller and user interface. The userinterface was displayed in a dynamic web to ease the user inmanaging the electrical devices and entering the room usageschedule. The power optimization system managed the electricalenergy from DPP by turning on the electrical devices according tothe priority value. The power optimization system tests were dividedinto six problems, of which each stage had an error value of 0%.

Dynamic programming algorithm is the classic method in distribution of plant loads. The traditional calculation method of dynamic programming is easy to make the calculation take too long time. This paper proposes two modiefied methods of dynamic programming, namely, dynamic programming in progressive structure and dynamic programming in progressive step-size. What is more, these two methods are combined to a new hybrid method. And these three methods and conventional dynamic programming are applied to the distribution of thermal power plant load to verify. The results of modiefied methods contrast with the conventional method show the modiefied methods reduce the calculation time and alleviate the curse of dimensionality effectively, ensuring the accuracy of calculation.

This research aims to the development of reader equipment as well as control the load limitation of electric power using Atmega 8535 microcontroller. In the development of equipment of reading and controlling electrical energy consumptions, the modified KWH (Kilo Watt Hour) meter was used by placing the optocoupler sensor as the enumerator indicator the electric power consumption on the disc. Atmega 8535 microcontroller was used to control and limitation of the electric power consumption. In this research, the measuring and control system was developed to record the amount of electrical power load used, and it can be used as an alternative to the current divider for the achievement of the efficiency of practical electrical energy consumption. The results of the measurement comparison between the measured load and the output load tended to be stable with an average percentage error of 6.3%, and it was still below the optimum threshold value of the error factor, which around 10%. Therefore, results of testing developed equipment KWH digital meter using Atmega 8535 microcontroller that was produced a good performance.

The purpose of this research was to investigate and compare the electrical power generation between the water weighted sun tracking system and the fixed installation system of the 1 MW solar power plant at Sirindhorn Dam. Two types of photovoltaic cell used in the water weighted sun tracking system were considered: multi-crystalline silicon and amorphous silicon. The results proved that the multi-crystalline silicon type produced 20.58% and the amorphous silicon type produced 16.57% more electrical energy than those of the fixed installation system, respectively. Overall, the water weighted sun tracking system generated 300,934.11 kWh/year more than that of the fixed installation system. The cost of the water weighted sun tracking system was 8.04 million bath and the payback period was 2.44 years, which was considered an attractive investment.

In this paper, the technical and economical feasibility study of the photovoltaic (PV) power plant at Bathinda city in the Punjab state of INDIA has been carried out. For this, solar irradiance of this location has been used to assess the annual solar energy potential of the selected site PV plant. The complete work has been carried out using PVsyst simulation software. This study has been carried out to feed the electrical energy generation deficit and the increasing future electrical energy demand of Punjab State. At present, Punjab State Power Corporation Limited (PSPCL) is paying ₹ 9.04 per kWh to the private players and the other states to procure electrical energy to meet the consumer load demand. In this work, it has been found that the actual cost to the company generating electrical power using PV is around ₹ 3 per kWh after including the capital cost, loan interests, depreciation, running charges and maintenance costs. So, the proposed PV generation setup definitely will prove to be beneficial for profit-making proposition for the company supplying electrical energy to PSPCL. Besides, reduction in carbon and GHG emissions with this proposed generation has also been evaluated, which will save the environment from global warming. This is due to the fact that most of the electrical power generation in the Punjab state of India is through thermal power

As electrical energy consumption has continued to rise in the United States, and producers of electricity search for power plants requiring less installation time, the gas turbine has emerged as a significant contributor to our nation’s energy needs. Despite a thermal efficiency disadvantage as compared to a conventional steam power plant, it has nevertheless played an increasingly larger role in the production of electrical power. A scheme is here presented whereby the output of a given gas turbine can be increased by more than 60% and its efficiency increased by 30%, thus making it more competitive efficiency-wise with the conventional steam power plant.

Coal is used all over the world to meet the energy needs of industry and housing and communal services. The main requirements of coal using are environmental safety and efficiency. Increasing these parameters can be realized with the combination of a gasifier and fuel cells. The paper includes a variant of the thermal scheme of the power plant, which uses coal as a fuel, with its further gasification and conversion into electrical energy in a solid oxide fuel cell (SOFC) stacks. The developed scheme differs from traditional circuits by using a gasifier with an inhibited circulating fluidized bed (ICFB). In addition, the anode-off gases are used in the combustion chamber of the gasifier to maintain endothermic gasification reactions. This technologies combination allows increasing the energy system efficiency. The paper also includes the results of tests of an ICFB gasifier and analyze the available electrical power of the SOFC stacks. Analysis dependence EMF from the produced generator gas composition showed no significant effect on the available power of the electrochemical generator. Developed scheme allow excluding from the process the gas cleaning from tar after gasifier, which allowed to increase the efficiency and reduce the metal capacity of the developed equipment.

False Sense

The traditional electric power load analysis (EPLA) uses a very basic routine of assigning demand factors to each connected electric load, then summing these to arrive at an estimated power plant load. This method is overly simplistic, gives a false sense of certainty, and does not accurately reflect vessel operations. This paper will describe an alternative to traditional methods of determining ratings and configurations for electric power plants during vessel concept and preliminary design. This method uses statistical methods to calculate a range of possible power plant demand. Resulting data can be used to evaluate power plant configurations with respect to design risk, vessel operating profiles, and potential limitations. The ability to better evaluate the complete range of required electric power across all operating profiles increases in importance as vessel power plants become more sophisticated with the introduction of variable speed generation, battery/hybrid power systems, DC power distribution, and distributed load centers.
