Research On Methodology Of Voluntary Emission Reductions For Photovoltaic Power Generation Projects

Climate change is one of the most severe global environmental issues faced by mankind in the 21 st century.Countries attach great importance to this and are conscientiously implementing measures to reduce greenhouse gas emissions.China has also adopted a series of measures,including the implement structural adjustments to reduce energy consumption and reduce greenhouse gas emissions.The active development of renewable energy such as solar energy to gradually reduce the proportion of coal-fired-based energy consumption in the power generation industry is a necessary and effective way to reduce greenhouse gas emissions.By focusing on the photovoltaic power plant project,with reference to the CCER methodology based on the emission reduction mechanism,this thesis analyzes the CCER methodology applicable to renewable energy power generation projects in China.Combining with the reality of photovoltaic power generation projects,it attempts to propose a CCER methodology for carbon emission reductions in photovoltaic power plants,including the comprehensive analysis of the identification and determination of the baseline scenario,and combining the examples of photovoltaic power plant project to verify the proposed method,and on this basis,the paper also explored Various influencing factors in the carbon emission reduction of photovoltaic power generation projects.Finally,from the perspective of the whole life cycle,this paper analyzes the carbon emission reduction effect of photovoltaic power generation system through the LCA evaluation method.The research in this paper provides reference for the quantitative assessment of the carbon emission reduction effect of China’s photovoltaic power generation projects and affirms the high-efficiency carbon emission reduction capability of the photovoltaic power generation system during the entire life cycle,which is of great significance to the development of photovoltaic power generation projects in China.The main conclusions reached at the end are as follows:1.Combining the actual conditions of China’s photovoltaic power generation projects,adaptability analysis was carried out in the six batches of voluntary emission reduction methodologies promulgated by the National Development and Reform Commission,including the identification of baselines,the determination of project boundaries,and the calculation of greenhouse gas emission reductions,and additional studies were conducted on the relevant sections where carbon leakage was not insignificant.2.Based on the calculation of carbon emission reduction of photovoltaic grid-connected power generation systems,the monitoring plans for carbon emission reduction projects and the parameters required for verification reports have been added,making the methodology more comprehensive in terms of monitorable,verifiable,and reportable.Make the MRV system of photovoltaic grid-connected power generation systems more robust.3.The LCA assessment method was used to analyze the total life cycle greenhouse gas emission reductions of photovoltaic grid-connected power generation systems.Through the establishment of a model,the GHG emission intensity per unit of electricity generated by the photovoltaic system is calculated to be 0.156 kgCO2/kWh,which is far less than the full life cycle emission intensity of the thermal power generation system,and its emission reduction effect is very significant.
