The large-scale integration of DC loads such as electric vehicles and air conditioners has increased the peak demand of the distribution network. Therefore, this paper proposed a load peak shaving operation management model based on interactive games among multi-stakeholder (e.g., distribution network operator, energy storage owner and electric vehicle users) in AC/DC hybrid distribution network. The supply and demand balance among multiple AC networks can be realized through DC network with the help of electric vehicles and energy storage when the distribution network operator adjusts the time-of-use electricity price in the peak shaving management model. Distribution network operators aim at minimizing the peak-to-valley difference and maximizing the operation revenue while energy storage owner and electric vehicle users seek for the greatest benefits in interactive game process. The above game model is constructed in a master-slave framework, where the existence and uniqueness of the game equilibrium is also proved. Finally, the numerical results show that the proposed operation management model can effectively reduce the peak-to-valley difference when ensuring the interests of all stakeholders.

A three-phase five-limb transformer is a potential application form of the Sen Transformer (ST), especially for the scenarios with significantly unbalanced load conditions. This paper proposes a quasi-steady-state model of three-phase five-limb ST (TPFLST) based on duality. Firstly, an equivalent circuit model that takes into account the eddy current effect and the coupling effect involving the magnetic circuit can be derived according to the equivalent magnetic circuit of the TPFLST. The iron-core of the TPFLST may be represented by the parallel combination of the resistances reflecting the power loss of the iron-core and the saturable inductances considering the ferromagnetic hysteresis in virtue of the principle of duality. Subsequently, an electric circuit model of the voltage and current of each winding for the TPFLST is able to be accomplished on the basis of the electrical connection between the TPFLST and the external systems in accordance with Kirchhoff's voltage and current law. Consequently, a quasi-steady-state model of the TPFLST which considers the coupling relationship involving the magnetic and electric circuits can be formed by combining the equivalent circuit model and the electric circuit model. With the help of MATLAB, the effectiveness of the proposed model may be verified by comparing the results about power flow control including power, voltage, and current with the ones from the existing literature. Furthermore, the TPFLST is found to be better-suited for the unbalanced load condition according to a comparison among the unbalanced degrees of output currents for the STs with different core structures under unbalanced load conditions.
