Problems solved by technology
[0003] However, the design of the frequency modulation control method and frequency modulation control system of the existing new energy power plants is not reasonable enough, and the output power of the new energy power plant cannot be adjusted according to the actual power consumption law of the user, and it does not have sufficient predictive effect, resulting in low energy utilization. , so we propose a primary frequency modulation control method and system for new energy power plants to solve the above problems

Description
A primary frequency modulation control method and system for a new energy power station technical field The present invention relates to new energy power generation technical field, relate in particular to a kind of primary frequency regulation control method of new energy power station and system. Background technique As an important indicator to measure power quality, grid frequency is related to the normal operation of electrical equipment and the user's Power quality. During the operation of the power system, the real-time and random changes of the power system load will cause the real-time and random changes of the power grid frequency. machine fluctuations. With the continuous expansion of the power grid scale, new energy power sources have become the main power sources of the power grid. Consumption of new energy power generation, the output of thermal power units has been continuously reduced, and even reduced the number of thermal power startups in some ar...
