Sliding mode control (SMC) is a promising robust control approach for the abrupt variations in complexsystem. Energy internet (EI), as a dynamic nonlinear strong coupling system, has different operating states underdifferent operating conditions (system connection, load levels and faults, etc.). We-Energy (WE), as a basic energyunit in EI, is proposed for describing the essential characteristics and operating state of EI. According the operatingstates of EI, four operating modes of WE presented in this paper can be randomly converted, which correspond thestochastic markov process. Then, based on the coupling characteristics of EI, a set of state equations is establishedto embody the markovian jumping system (MJS) of WE. Moreover, sliding surface and contorl scheme for WEbased on MJS is designed. Finally, a numerical simulation is shown to illustrate the proposed method.
