Power distribution network power supply guaranteeing method based on electric engineering vehicle

Abstract

The invention discloses a power distribution network power supply guaranteeing method based on an electric engineering vehicle. The method comprises the following steps: configuring electric vehicles with different scales, vehicle types and battery capacities as the electric engineering vehicle in combination with the maintenance environment, the type, the historical data influencing the user degree and the market condition of the electric vehicles; presetting a charging mode of the electric engineering vehicle; establishing an electric engineering vehicle optimization scheduling model according to the electric engineering vehicle travel overhaul and power failure load requirements; planning an optimal driving route by adopting a simulated annealing algorithm in combination with the charge state and the road condition information of the electric engineering vehicle; connecting an electric engineering vehicle power supply to the user low-voltage power distribution system, and switching to an inversion discharge mode to supply power to a load; and according to a power failure area load curve predicted by a dispatching center of a power grid company, calculating a minimum power deviation under a set constraint, and calculating an optimal battery output power of the electric engineering vehicle. The power demand of the user during the power failure is guaranteed, so that the power supply reliability of the power distribution network is improved.

Description

technical field [0001] The invention relates to the technical field of guaranteed power supply of a distribution network, in particular to a method for ensuring a power supply of a distribution network based on an electric engineering vehicle. Background technique [0002] With the development of electrification and intelligence, electricity plays an extremely important role in the field of construction and development. But in life, the possibility of power outages for users always exists. At present, measures to improve the reliability of low-voltage distribution network power supply mainly include: improving the automation level of distribution network, improving the distribution network structure, replacing pole-mounted distribution transformers with substation kiosks or box-type transformers, and configuring user-side energy storage equipment , Generator car protection power supply, etc. Some of the above-mentioned measures are large in scale and high in cost, and it i...
