HS Solar Energy Company Inc. in Sejong city, Korea, has a big problem on how to monitor heterogeneous inverters with different protocols. Still a current photovoltaic power plant with different inverters, it has attracted significant attention to its experience of difficulties in monitoring integrated power generation. To solve this problem for the company, we adapt a metamodel mechanism to easily manage and integrate heterogeneous data into a metamodel-based data format. The existing metamodel-based photovoltaic monitoring system (M-PVMS) of the HS solar energy company also needs to simply predict the photovoltaic power generation in a day for small farm owners in the countryside. Therefore, we propose a method for predicting the power generation of M-PVMS panels using the gated recurrent unit (GRU) algorithm, which supports real-time learning to predict the photovoltaic system behavior that rapidly accumulates data in real time. As a result, we can predict the power generation for small farm owners with a probability of 96.353%.

The healthcare facilities sector is an energy-intensive organization especially at a time of spreading dangerous infectious viruses, such as new Coronavirus, or what is known as COVID-19. Recently, many countries have opened several mobile field quarantine hospitals provided with the required technical equipment to prevent the COVID-19 outbreak in these countries. Unfortunately, most of these healthcare camps are lacking in the application of the necessary sustainability principles and health standards to become green healthcare facilities. Solar energy can be used for various purposes in green healthcare facilities, such as power generation and other sterilized applications. Therefore, in the present paper, a new design for the mobile, quick built, and solar-powered green healthcare camp, in safe and effective 24 hours a day services, is introduced. The proposed green healthcare camp is built using modern building technologies for rapid constructions, in which the building design is proposed to incorporate the photovoltaic power generation consideration. Photovoltaic systems are designed according to the loads required for the operation of the designed model of the green healthcare camp. Moreover, the total cost of a solar-powered green healthcare camp is estimated according to local conditions and standards in Saudi Arabia. The practical recommendations are presented with the designed photovoltaic system to attain the overcurrent and overvoltage protection. The photovoltaic designed system is proposed under the condition of ascertaining the service continuity of the photovoltaic power system during the electric faults in the photovoltaic strings. This is achieved by incorporating series diodes at the terminals of each photovoltaic string. The performance of a 50-kW PV system simulated using Matlab/Simulink is evaluated for the fault disturbance to enhance the service continuity.

As the development trend of solar energy, which is a green way of energy utilization, photovoltaic power generation has been a research hotspot of solar energy utilization technologies. Using the concentrating and tracking technology to increase the illumination intensity, and obtain more electrical energy, that will reduce the cost of the photovoltaic power generation system sharply. A kind of steric and multilevel concentrator for photovoltaic generation is introduced in this paper, whose concentration ratio is 3. The operating factor of plane mirrors and performance price ratio of the system is increased for optimizing the condensation parameters and structure of the concentrator.

Solar energy is an inexhaustible and renewable energy without environmental pollution. Solar energy can be used in three kinds of forms: solar thermal energy, photochemical conversion and photovoltaic power generation. Among these, the final form of photovoltaic power generation is electricity which can be transported, applied and stored conveniently. On the basis of photovoltaic effect, solar cell is developed as a new technology to convert light energy into electrical energy using semiconductor. Up to now the two key problems of the development of solar cells are how to improve the conversion efficiency and reduce cost. Therefore, the material and production technology used for solar cells are discussed based on improving conversion efficiency in this article.

The distributed power generation is an energy development way which can most manifest the multiple advantages such as the energy saving, emission reduction, safety and flexible trait. As a kind of distributed power generation technology of renewable energy, photovoltaic power generation has already transited from supplement energy to alternative energy. Although solar photovoltaic power generation industry develops very quickly in China, actual application cases of substation photovoltaic grid-connected power generation system are few. In this paper, the research of photovoltaic grid-connected power generation system is used in Zhuishan substation in Bengbu Anhui province. The system is the first set of substation photovoltaic-connected grid power generation system in Anhui province. It has being operated for three years safety and steady. The whole application of the system is advanced and groundbreaking in the domestic.

The large-scale grid connection of photovoltaic power generation results in the power system frequency fluctuation and frequency regulation capacity decline, which endangers the dynamic security of power grid frequency. In order to reduce the frequency deviation of power grid and tap the potential of photovoltaic power generation participating in frequency regulation, a control method of photovoltaic power participating in frequency regulation of power grid is proposed in this paper. The maximum allowable power of photovoltaic power is predicted through system identification, and the load shedding rate is determined based on this, and the output power is corrected according to the system frequency deviation to participate in frequency regulation of power grid. The model based on MATLAB Simulation results shows the effectiveness of the proposed method.
