Efficient Power

With the increasing consumption of fossil energy and changes in the ecological environment, meeting the energy demands required for industrial and economic development with clean and efficient power generation is a major challenge of our society. Solar energy is considered to be one of the most renewable and sustainable energy sources, and photovoltaic power generation has become an important research topic. This study combines data envelopment analysis (DEA) with Tobit regression analysis to assess the efficiency of photovoltaic power generation in China and analyze factors affecting efficiency to improve the efficiency of photovoltaic power generation. The results show that there are obvious regional differences in photovoltaic power generation efficiency in China. The phenomenon of focusing on economic development at the expense of the use of solar power generation still exists. The establishment of photovoltaic demonstration projects, the implementation of differential electricity price policies, and the promotion of photovoltaic precision poverty alleviation can alleviate economic pressure and effectively improve the efficiency of photovoltaic power generation.

Temperature is one of the important factors affecting the power generation efficiency of PV cells. In order to improve the efficiency of photovoltaic power generation systems and heat utilization efficiency, we used Matlab/Simulink to build photovoltaic power system analysis model based on thermal power. By changing the heat and illumination input to the photovoltaic cell model and the heat generated by the battery we got the characteristics and temperature characteristics of the photovoltaic cell the system model, the photovoltaic power generation system model and the output power correction, etc. We got the environmental temperature change equation through the actual air temperature and curve fitting and used real and detailed data to compare the data obtained using the equation for online correction. PV cells temperature factor was used to get the PV cells temperature with the environment temperature changes. In order to get PV module thermal /energy efficiency the dates was processed and analyzed by using Matlab and Excel through actual observation data of school 120KW PV power station. The results showed that power generation efficiency increased and year average efficiency PV improved 21.3279% through the use of some heat about PV cells.

The Relationship

The performance of magnetohydrodynamic (MHD) power generator is affected by many issues, among which the load coefficient k is of great importance. This paper reveals the relationship between the k and the performance of MHD generator by numerical simulation on Faraday-type MHD power generator using He/Xe as working plasma. The results demonstrate that the power generation efficiency increases with an increment of the load factor. However, the enthalpy extraction firstly increases then decreases with the load factor increasing. The enthalpy extraction rate reaches the maximum when the load coefficient k equals to 0.625, which infers the best performance of the power generator channel with the maximum electricity production.

Simulation Results

In this paper, photovoltaic power generation(PV) and the asynchronously grid-connected power grid are taken as the research objects, and the frequency adaptability of PV to power grid is studied. The influence mechanism of grid frequency variation on PV is revealed, and it is proposed that the frequency tolerance range of PV is mainly determined by the setting value of inverter protection and PLL parameters. The whole process simulation of wind turbine adaptability under frequency change is realized on Matlab/Simulink, and the simulation results verify the correctness of the conclusion.
