Application of Grey Markov Chain in Statistics Low Voltage Photovoltaic Energy Abandonment Statistics
The abandoned power of low voltage distributed photovoltaics,as an important criterion for regional division and energy storage capacity configuration,has long been unable to be accurately calculated.Starting with the source network load storage system,a low-voltage distributed photovoltaic curtailment statistical model is established based on grey Markov chain.The dual scenario of"weather+time"is used to construct a state transition matrix to statistically analyze the low voltage distributed photovoltaic energy abandonment.The test results show that the proposed method can accurately obtain low voltage distributed photovoltaic energy abandonment data and control the maximum error within 5％,which has certain promotional value.
