The wind solar hybrid power generation is still seriously affected by the weather

with a certain degree of intermittence and instability. In order to meet the needs of grid security and stability better

wind-solar-battery hybrid power generation can compensate for weather instability.In order to promote the exchange of ideas and development of the control technology in wind-solar-battery hybrid power system

one of the equipments of the national vocational students’ skills competition named the design and implementation of photovoltaic electronic engineering is used with the prototype of microgrid new energy station. According to the control requirements of wind-solar-battery hybrid power system

the configurations of input and output ports of PLC are listed

and a general idea of the programming process is provided on the basis of the task. Compared to the regular PLC ladder diagram

this paper uses the C language function block which reduces the memory usage from 21% to 13%

which makes the system more stable and reliable.
