1Object-affected harmful factors
If photovoltaic power generation is used to replace fossil fuels, then environmental pollution is reduced and renewable energy is utilized, but the randomness, volatility, and uncertainty of photovoltaic power generation create challenges for power system operation
Solution Approach 1:
The patent applies preliminary action by determining a representative scene year and pre-calculating available generating capacity based on historical weather data before actual power system operation. This advance preparation allows the power system to account for photovoltaic variability in advance, improving operational reliability while maintaining renewable energy benefits
2Productivity
If capacity calculation methods are simplified for ease of use, then operational efficiency is improved, but measurement precision and accuracy of capacity calculations deteriorate
Solution Approach 1:
The patent uses copying by creating a representative scene year that replicates typical weather patterns and generating conditions. This virtual copy allows accurate capacity calculation without requiring complex real-time simulations, thus maintaining measurement precision while improving operational efficiency through simplified calculation processes
