一种考虑光伏容配比的区域电网电力平衡预警方法
By analyzing historical data of the regional power grid and photovoltaic-related parameters, the power surplus/deficit values and tie-line transmission power are calculated. A photovoltaic capacity ratio adjustment strategy is proposed, which solves the impact of photovoltaic capacity ratio changes on power balance and achieves more accurate power grid early warning and grid structure optimization.

AI Technical Summary
Existing technologies fail to effectively consider the impact of changes in photovoltaic capacity ratio on photovoltaic output and the simultaneous output rate of small areas, resulting in inaccurate power balance analysis of regional power grids.
By acquiring historical operating data of the regional power grid system, we can calculate photovoltaic-related parameters such as capacity ratio, conversion efficiency, and output simultaneity rate, analyze power surplus/deficit values and tie-line transmission power, propose a power balance risk early warning method, and adjust photovoltaic development strategies based on simultaneity rate deviation indicators.
It improves the accuracy of regional power grid power balance early warning, helps planners optimize grid structure and new energy development, and reduces power balance risks.
