Energy Type

As one of the world’s largest energy consumers, China is facing the challenge of growing energy demand. Under this background, China is actively implementing the concept of green development and sustainable development route. As inexhaustible green energy, solar energy, has been established as an independent energy type by the Renewable Energy Law and has a broad development prospect. At present, the industrialization level of photovoltaic manufacturing in China is constantly improving, and the efficiency of photovoltaic power generation is constantly improving. However, from the perspective of the system, China’s photovoltaic industry supporting legal system is not perfect. There is a mismatch between the existing laws and industrial development needs, which restricts the future development of photovoltaic power generation in China. The legal environment is crucial to the development of a country’s relevant industries. Only with a good supporting legal system can the development and utilization of solar energy be carried out reasonably and orderly. The PV industry legislation should be adjusted and responded to in a timely manner according to the development situation of the PV industry and the PV market, so as to speed up the introduction of core laws in the PV field, continuously improve the supporting legal system, and effectively play the role of institutional protection of the law.

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.

Currently, Afghanistan imports a high percentage of electric energy from the neighboring coun-tries, while less attention has been paid on the utilization of internal domestic energy resources. Recently progress has been made with solar and wind energy, but other sources such as hydro energy remain underappreciated. Originally intended as a short-term solution to fulfill demand, the policy for importing power from neighboring countries is still in effect as energy demand has increased dramatically and exposed vulnerabilities in the existing power system. These issues can be categorized based on different aspects like technical, economic, political, security-related issues, natural disasters and many others that negatively affect the reliability of the energy sector. In this paper, the sustainability of the power system of Afghanistan is analyzed from different aspects. These multi-disciplinary problems are analyzed separately and linked with the weaknesses of the existing power system. The main objective of this study is to propose long-term solutions to the power sector by encouraging investment in the internal power generation to enhance sustainability and reliability. The proposed long-term solution also takes additional measures towards achieving sustainable development goals (SDG) such as economic growth, agricultural development, ground-water recharge, industrial development, flood and water control, job creation, and a green and clean environment.

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.

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%.

Since the industrial revolution, the world’s economy has mainly relied on the consumption of fossil fuels. The burning of coal releases vast amounts of toxic COx greenhouse gasses into the atmosphere that bear an undesirable environmental impact. The ongoing offshore oil exploration activities; the infrastructure for oil extraction, production, and transportation; and the inevitable oil spills cause severe damage to the environment and huge loss of sea life, flora, and fauna. Recent awareness of the environmental issues and the worldwide climate change spurred public interest in clean and environmentally friendly “green” energy generation. Solar energy is an abundant and inexhaustible resource that can meet much of the worlds’ energy needs and, thus, has been in the focus of scientific attention for many years. Yet, converting solar energy into usable electric power is a formidable engineering and economical challenge. The recent environmental awareness triggered governments and private companies around the world to encourage further research and capital investment into the development and deployment of efficient and cost-effective solar technologies. This review reports on advances in the technological approaches that can be employed to convert sunlight to electricity. This article presents a short survey of the state-of-the-art architectures of photovoltaic arrays and a review of the concepts and strategies of their associated electronic power processors for solar energy generation. The paper aims to be of assistance to engineers and scientists who are already engaged or just joining this fascinating field, to promote the knowledge of photovoltaic energy and facilitate the proliferation of the solar power generation systems.
