Embodiment Construction
[0075] The present invention is an evaluation method for analyzing the income of a photovoltaic power generation project based on the user's electricity consumption characteristics, comprising the following steps:
[0076] S1. Select the measurement area, calculate the sunshine time, weather conditions, and temperature of the area, and evaluate the photovoltaic power generation;
[0077] S2. Collect real-time power consumption data of users in the area, perform cluster analysis on users with different power consumption characteristics, and divide all users with different power consumption characteristics into categories with different peak-to-valley time periods; the peak-to-valley time periods Refers to the peak time period, flat time period, and valley time period;
[0078] S3. Analyze the photovoltaic power generation and power consumption of various users during the peak and valley periods, and calculate the annual self-consumption ratio of photovoltaic power generation fo...

The invention discloses an evaluation method for analyzing the income of a photovoltaic power generation project based on user electricity consumption characteristics, including: selecting a measurement area, calculating the sunshine time, weather conditions, and temperature of the area, and evaluating the photovoltaic power generation amount; Electricity data, cluster analysis is performed on users with different electricity consumption characteristics, and all users with different electricity consumption characteristics are divided into categories with different peak-valley time periods; the peak-valley time period refers to peak time period, average time period Period and valley time period; analyze the photovoltaic power generation and power consumption of various users in the peak and valley time periods, and calculate the annual self-use proportion of photovoltaic power generation for various users; calculate the photovoltaic power generation status according to the annual self-use proportion of photovoltaic power generation for various users The total income of photovoltaic power generation can be obtained by calculating the electricity cost saved, the income of on-grid electricity, and the total power generation subsidy, which provides a basis for customers to invest in photovoltaic power plants.
Description
technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to an evaluation method for analyzing the income of a photovoltaic power generation project based on user electricity consumption characteristics. Background technique [0002] With the country's strong support for new energy, the photovoltaic industry has developed rapidly, and more and more people tend to invest in their own photovoltaic power plants. In order to recover the investment cost as soon as possible, photovoltaic users often adopt the method of converting solar energy into electric energy for self-use, and the surplus can be supplied to the nearby low-voltage public network, that is, the investment model of "spontaneous self-use and surplus electricity connected to the grid". But in fact, for photovoltaic users with different electricity consumption characteristics, the evaluation methods of photovoltaic revenue are often different. Among the current existi...
