Abstract This paper mainly introduces a comprehensive solar energy utilization system with low-CPC and polycrystalline silicon solar photovoltaic components. Outdoor experiments have been made to test the electrical efficiency, heat efficiency and their changes of the system with fixed temperature of outlet water and different sunshine conditions. Besides, this paper also compares the effects of outlet water at various temperatures on the efficiency of the whole system as well as the temperatures and flow rate responses with different PID parameters. Through analysis of these experimental data, the most desirable temperature of outlet water and PID parameters have been obtained in CPC-PV/T Hybrid Thermal-electric System, thus providing references for relevant experimental research.

This paper proposed using solar energy as the auxiliary heat source of coal-fired power plants’ auxiliary steam system based on the current status of the coal-fired power generation and solar energy utilization. Taking a 600MW coal-fired power unit as an example to analysis, it is shown that the thermal performance of the integrated system is improved and the coal consumption rate declines, which radically reduces power plants’ emissions of greenhouse gas and pollutants.

New Framework

The relevance of focusing on SPV systems with storage to meet the user specific requirement is discussed}. Existing Solar Photovoltaic (SPV) systems are studied and the need for introducing new classification based on the interaction with utility grid, solar module and battery backup, based on load types and end user application is proposed. In order to represent the entire SPV systems a generic framework is introduced known as the three-switch model. All the SPV systems under the new classification can be represented using the framework by changing the switch states. Using this framework, a method to convert existing backup systems into a grid-interactive system is proposed. The ways to enhance maximum solar utilization, utility savings and system reliability are discussed. The states of the grid-interactive systems are discussed and simulated using Typhoon HIL 600

Abstract The study evaluates the visibility of solar photovoltaic power plant construction for electricity generation based on a 20 MW capacity. The assessment was performed for four main cities in Iraq by using hourly experimental weather data (solar irradiance, wind speed, and ambient temperature). The experimental data was measured for the period from 1st January to 31st December of the year 2019, where the simulation process was performed at a 1 h time step resolution at the same resolution as the experimental data. There are two positionings considered for solar photovoltaic modules: (i) annual optimum tilt angle and (ii) two-axis tracking system. The effect of the ambient temperature and wind on the overall system energy generated was taken into consideration. The study is targeted at evaluating the potential solar energy in Iraq and the viability of electricity generation using a 20 MW solar photovoltaic power plant. The results showed that the overall performance of the suggested power plant capacity is highly dependent on the solar irradiance intensity and the ambient temperature with wind speed. The current 20 MW solar photovoltaic power plant capacity shows the highest energy that can be generated in the mid-western region and the lowest in the northeast regions. The greatest influence of the ambient temperature on the energy genrated by power plants is observed in the southern regions.
