An evaluation method for analyzing photovoltaic power generation project income based on user power utilization characteristics

Abstract

The invention discloses an evaluation method for analyzing photovoltaic power generation project income based on user power utilization characteristics, which comprises the following steps: selectinga calculation area, calculating the sunshine time, weather conditions and temperature of the area, and evaluating the photovoltaic power generation amount; Acquiring real-time power consumption data of users in the region, performing clustering analysis on the users with different power consumption characteristics, and classifying all the users with different power consumption characteristics intocategories with different peak-average-valley time periods; Wherein the peak flat valley time period refers to a peak time period, a flat time period and a valley time period; Analyzing the photovoltaic power generation amount and the power consumption amount of each type of users in the peak-average-valley time period, and calculating the annual photovoltaic power generation self-use proportionof each type of users; According to the annual photovoltaic power generation self-use proportion of various users, the electric charge saved in the photovoltaic power generation state, the grid-connected electric quantity income and the total power generation amount subsidy are calculated, the total photovoltaic power generation income is obtained, and a basis is provided for the client to investa photovoltaic power station.

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...
