Abstract
A distributed optimal control technology of AC/DC hybrid distribution network voltage considering active re-sponse is proposed.According to the current injected into the AC/DC hybrid distribution network,the node voltage of the distribution network is obtained by using the conductance matrix.By constructing the power equation of the distribution network,the power flow calculation result is obtained,and the power loss of the AC/DC hybrid distribution network is calculated.The voltage of AC/DC distribution network is processed identically by using the droop relationship between voltage and power,and the interactive support control is achieved by using the power reference signal of interactive sup-port control of distribution network.According to the relationship between maximum output voltage and minimum switc-hing loss of distribution network,the voltage utilization rate of active response control is used to synthesize the required DC link average voltage,and the distributed optimal control of AC/DC hybrid distribution network voltage is realized.The experimental results show that the proposed method can effectively control the voltage of AC-DC hybrid distribution net-work and improve the voltage control accuracy.
