Prediction of Photovoltaic Power Generation Based on SCC-CNN
Solar power forecasting will have a significant impact on the future of large-scale renewable energy plants. Predicting photovoltaic power generation depends heavily on climate
Author to whom correspondence should be addressed. With the large-scale integration of renewable energy into the grid, traditional short-circuit current (SCC) calculation methods for synchronous generators are no longer applicable to inverter-based non-synchronous machine sources (N-SMSs).
The main method currently used for calculating SCC in renewable power plants is the equivalent method. This study proposes a practical method called the single-machine multiplication method, combined with the traditional SCC calculation approach for synchronous generators, to introduce a local iterative method for the fault region .
Improved accuracy in fault detection and SCC estimation enhances the design, protection, and operation of renewable power plants. It allows for more reliable protection systems, reduced costs, and more efficient integration with the grid.
Then, a single-machine steady-state SCC calculation model is proposed. Based on the classification of N-SMSs, a practical SCC calculation model for renewable power plants is introduced, balancing accuracy and computational speed. The feasibility of the model is validated through simulations.
