Abstract
- Compared with the AC distribution network, the DC distribution network has the advantages of lower line losses, better power quality, higher reliability and being suitable for all kinds distributed generation and DC load access, etc. This paper firstly studies the models of PV and energy storage connected to the DC distribution network. Then, a new type of DC distribution network topology with hybrid DC circuit breaker is proposed. A coordinated control strategy is also proposed, which can control energy storage to improve the stability of the system. Finally, using PSCAD/EMTDC to model and simulate. The simulation results show that the proposed topology of DC distribution network and control strategy can quickly remove the fault, shorten the fault power failure time and ensure the safe and stable operation of the system, which greatly improves the operation efficiency and safety level of the power grid.
