AI Technical Summary
In existing technologies, the high proportion of renewable energy connected to the distribution network leads to voltage and current exceeding the limit, and there is a lack of research on the comprehensive management of active and reactive power, especially the lack of day-ahead and intraday two-stage optimization operation methods based on integrated regulation devices.
A two-stage distribution network integrated regulation device is adopted, which acquires photovoltaic-load forecast data, establishes an optimized operation objective function and constraints, performs day-ahead active and reactive power integrated regulation, and combines intraday rolling optimization to optimize active and reactive power output, thereby reducing network losses and operating costs.
While ensuring the grid voltage operation requirements, reduce the distribution network loss and the operating cost of integrated regulation devices to achieve stable operation under a high proportion of photovoltaic access.
