How to calculate the subsidy benefits for distributed photovoltaic power generation owners?
The subsidy benefits for distributed photovoltaic power generation owners are divided into three parts: 1. National subsidies; 2. Electricity expenses offset by spontaneous self use; 3. Electricity price for purchasing desulfurization coal.
The ways in which distributed photovoltaic power generation systems are integrated into the power grid are specifically divided into three types: all self use (all generated electricity is supplied to one's own load), self use surplus electricity is connected to the grid (priority is given to supplying one's own load, and excess electricity is connected to the national grid), and all connected to the grid (all generated electricity is connected to the national grid).
According to different grid connection modes, the profit calculation method is as follows:
1. The subsidy benefits for self use are: (local electricity price+national subsidy for distributed photovoltaic power generation) × Total power generation;
2. The subsidy income for self use surplus electricity connected to the grid is: (proportion of self use) × Local electricity price+national subsidy for distributed photovoltaic power generation+proportion of grid connection × Electricity price for purchasing desulfurization coal) × Total power generation;
3. The total subsidy income for grid access is: (National subsidy for distributed photovoltaic power generation+purchase price of desulfurization coal) × All power generation.
