There is also KPI in the sun?Please check this transcript

"The average number of annual utilization hours of photovoltaic power stations in Hangzhou's investment in the city of Hangzhou is 881 hours. The average number of hours of photovoltaic photovoltaic annual utilization is 864 hours ... "

At the end of July, Hangzhou Energy Data Evaluation and Application Research Center launched the "Hangzhou Photovoltaic Operation Monitoring Analysis and Development" Energy Efficiency File ". Based on the operation data of 33,000 photovoltaic users, the photovoltaic efficiency decay evaluation model was established, and photovoltaic power generation was carried out. Effective monitoring and evaluation for the reference of the government and the society.

Not long ago, Hangzhou issued a high -temperature red warning signal for four consecutive days. The scorching sun that allows most people to retreat from the three houses is the source of energy for the photovoltaic power station. At the same time, in the context of vigorously promoting the construction of new power systems, the development of clean energy has entered the fast track, and Hangzhou is increasing the efforts to implement the photovoltaic multiplier plan. It is expected that the new photovoltaic power generation capacity will be 400,000 kilowatts a year. So, for each photovoltaic power plant, how to objectively evaluate the effectiveness of photovoltaic power generation? How to accurately position low -level photovoltaic and improve the efficiency of photovoltaic power generation?

In order to solve the above problems, the Hangzhou Energy Data Evaluation and Application Research Center launched the "Hangzhou Photovoltaic Operation Monitoring Analysis and Development" Energy Efficiency Archives "to help the potential of the local photovoltaic power station. The professional team starts from three links: effective effectiveness, calculation benefits, and proposal. The two core factors of "annual utilization hours and photovoltaic efficiency attenuation rate" are comprehensively divided into four types: "red, orange, yellow, and green". The four colors represent the urgent level of the photovoltaic power plant urgently needed to improve operation and maintenance. Among them, red represents the most urgent and decreased in order. Based on this, for 33,000 photovoltaic projects to generate visualized "Photovoltaic Health Reports" one by one, it proposes intelligent management solutions such as intelligent operation and maintenance, technical reform and upgrading, and retreating.

The Hangzhou Energy Big Data Evaluation and Application Research Center proposes intelligent management solutions such as intelligent operation and maintenance, technical reform and upgrading, and retreating.

Taking the 8700 -kW distributed photovoltaic power generation project on a roof of a building in Hangzhou as an example, the analysis of this photovoltaic operation "energy efficiency file" pointed out that the power station has been launched for 4 years, and the efficiency of power generation has gradually declined, and it is urgent to improve operation and maintenance. The Hangzhou Energy Data Center immediately designed the operation and maintenance improvement plan for it, and calculated that if the intelligent operation and maintenance management was improved, the annual power generation utilization of the photovoltaic power station was expected to increase to 998 hours, exceeding the average level of Hangzhou, and the annual issuance of green power 97 was issued. Thousands of kilowatt hours help users increase their income by 400,000 yuan.

This file also estimates that if the low -level photovoltaic management of low -level photovoltaic in 33,000 photovoltaics will increase the amount of green electricity and electricity each year, 280 million kWh will be reduced, and carbon emissions will be reduced by 148,000 tons. 100 million yuan, "Power Generation Online" users are expected to increase their income by about 19 million yuan each year, with significant investment benefits.

Dr. Chen Lin, the State Grid Hangzhou Power Supply Company Economic Research Institute, introduced: "In the context of creating a model of new electricity systems in the city, we break the problem from the perspective of the potential of local new energy resources, and the historical operation data of the live photovoltaic project is the key On the one hand, help local green power to increase, and on the other hand, add costs to users. "

"At present, Hangzhou's local photovoltaic power generation capacity has exceeded 1.7 million kilowatts, which has become the second largest power supply in Hangzhou, and its development has developed rapidly. At the same time, photovoltaic development has also entered the stage of" mass quality ". After the current level of the Hangzhou photovoltaic photovoltaic efficiency, it is used with digital methods to screen projects with low effectiveness. At the same time, a feasible improvement plan is proposed to help the government master the development of photovoltaic development and provide a reference for formulating relevant policies and rules in the next stage. The healthy development of local new energy. "Liu Aixin, the Energy Department of the Hangzhou Development and Reform Commission, commented.
