Embodiment Construction
[0010] The present invention comprises the following steps:
[0011] Step 1: Establish a probabilistic continuous power flow model for the electric-gas coupling system;
[0012] The present invention studies the uncertainty of wind farm output, and uses a two-parameter Weibull distribution model to describe the random variation law of wind speed v, and the output power P of wind power generator W . The modeling of wind turbines has been widely studied, and the present invention will be directly applied, and the details will not be repeated.
[0013] The following formula represents the wind power electric-pneumatic coupling system with parameters and power flow equations:
[0014]
[0015] In the formula, P Gi ,P Li , Q Gi , Q Li Represent the active power, active load, reactive power and reactive load from the generator at the initial point respectively; V i , θ i respectively represent the node voltage and node phase angle; A is the branch node correlation matrix ...
