The 10th step: judge the power grid security level: electrical network is carried out safety and stability evaluation according to the peak load regulation network scheme, if electrical network satisfy safe and stable operation various constraints and N-1 static security assessment, then export the value of exerting oneself and peak load regulation network scheme that wind-powered electricity generation online power allows, and entered for the 19th step; If the safety and stability evaluation existing problems, promptly electrical network is dangerous, then enters for the 11st step
In the 11st step, determine the electricity net safety stable problem: judge that when the 10th step there is safety problem in electrical network, then propose concrete problem, and possible solution, entered for the 12nd step.
In the 12nd step, increase power grid security constraints: propose influence the problem and the measure of electric power netting safe running, and be constraints, return the 8th and go on foot with the measure.
The 13rd step, control wind-powered electricity generation unit output: owing to predict the outcome according to the ultrashort phase of wind-powered electricity generation, electrical network does not possess peak modulation capacity, with the possible peak modulation capacity of electrical network as constraints, provide electrical network and possess the wind-powered electricity generation online power that allows under the peak modulation capacity condition, entered for the 14th step.
Whether in the 14th step, judge that wind-powered electricity generation is exerted oneself can control: wind-powered electricity generation is exerted oneself and only may be reduced, and can not increase, so relatively control the size of exerting oneself with predicted value and get final product.Predicted value is big, illustrates that then directly the control wind power gets final product, and enters for the 15th step; Predicted value is little, and then explanation need be taked load shedding or call emergency control measure such as other power supplys, enters for the 16th step.
In the 15th step, control wind-powered electricity generation online power: the result is this step result output with the output of the 13rd step, returns for the 6th step.
In the 16th step, given electrical network emergency control: the wind-powered electricity generation online ultrashort phase of power according to satisfied the 6th step output predicts the outcome, and to call emergency use earlier, the principle of load is limited in the back, provides the emergency control measure that electrical network must be taked, and returns for the 7th step as condition.
In the 17th step, manual setting wind-powered electricity generation online performance number: selected the off-line research mode of manual setting in the 1st step, the artificial given wind-powered electricity generation online power of wanting under the research mode in this step directly entered for the 6th step and and the result is exported to the 14th goes on foot.
The 18th step, manual setting power system operating mode: the off-line research mode of in the 1st step, having selected manual setting, the artificial given power system operating mode that will study in this step, can make amendment under the real-time power network operational mode obtains, and the result was exported to for the 7th step.
The 19th step, output final result: after estimating by power grid security in the 10th step, the wind-powered electricity generation online power and the peak that allow are exported as final result, also will be exported the emergency control measure to what taked the electrical network stringent effort.
