The invention discloses a double-chain Markov electric vehicle load modeling method considering a complex trip chain. The method comprises the following steps: obtaining travel data of electric vehicles in residential areas, specifying vehicle form destination types, and fitting to obtain internal and external travel factor feature data; dividing the state space of the electric vehicle; constructing an electric vehicle complex trip chain by using internal and external trip factors of the electric vehicle cluster; solving a multi-state electric vehicle double-chain Markov one-step transition probability matrix; and constructing a double-chain Markov electric vehicle load model considering the complex trip chain. According to the method, the double-chain Markov theory is adopted, the key influence of the complex trip chain under the trip internal and external factors of the electric vehicle user on the electric vehicle cluster modeling is considered, the electric vehicle load model considering the complex trip chain based on the double-chain Markov theory is established, the rationality and precision of the electric vehicle load model are improved, and the electric vehicle cluster modeling efficiency is improved. And the interaction between the electric vehicle and the power grid and the capability of participating in power grid dispatching are enhanced.
