Power distribution network relay protection method considering vehicle-network interaction under high-proportion new energy access

The invention discloses a power distribution network relay protection method considering vehicle-network interaction under high-proportion new energy access, and the method comprises the steps: simulating and analyzing the travel behaviors of all electric vehicles in a designated region within one day, and determining the discharge power of all electric vehicles at each moment in one day; determining charging and discharging rules of the electric vehicles, and determining areas and charging and discharging states of all the electric vehicles at all moments in a day in combination with travel behaviors of all the electric vehicles in a specified area; the total discharge power of the electric vehicle in each region at each moment is the equivalent distributed power supply output power in each region at each moment; calculating energy conversion power of the new energy at each moment according to the weather and meteorological data and the new energy equipment parameters, and accessing the energy conversion pow
