Charging pile cluster emergency scheduling control method based on travel characteristics of electric vehicles

Abstract

The invention discloses a charging pile cluster emergency scheduling control method based on travel characteristics of an electric vehicle, which is applied to a power grid operation control system, a power grid operation management platform and a V2G charging pile, and comprises the following steps: the power grid operation management platform obtains operation information of the V2G charging pile accessed to a power grid at any time, and stores the total information into a historical database; real-time information such as charging pile real-time power information, SOC state, charging power upper and lower limits and the like is sent to a power grid operation control system; vehicle travel characteristic indexes are established, and the power grid operation management platform periodically updates the vehicle travel characteristic indexes according to the vehicle travel data of the historical database; establishing a charging pile cluster emergency regulation and control strategy model; and when the power grid breaks down, the power grid operation control system outputs an emergency power regulation target value for determining the charging pile cluster according to the system fault condition, calls the charging pile cluster emergency regulation strategy model, calculates a charging and discharging power instruction value of the charging vehicle, and issues the charging and discharging power instruction value to the charging pile for execution.

Description

technical field [0001] The invention relates to the technical field of power grid operation, in particular to a charging pile cluster emergency dispatch control method based on electric vehicle travel characteristics. Background technique [0002] A large number of electric vehicles are connected to the grid for charging and the charging power is increasing, which brings severe challenges to the grid. The connection of electric vehicles with large-scale and high charging power to the power grid will cause negative impacts on the power system, such as peak load, energy transmission loss, voltage drop, mobility of distribution network flow, and difficulty in distribution network dispatching and control. After clarifying the impact of electric vehicles on the power system, the academic community has begun a series of research on the orderly charging and discharging strategies of electric vehicles, research on methods and strategies for electric vehicles to participate in the de...

Problems solved by technology

For example, the public orderly charging method based on load forecasting does not take into account the impact of time-of-use electricity prices on user charging behavior; the public electric vehicle participation in load stabilization strategy does not consider the vehicle's driving behavior characteristics; most vehicle-network interaction methods And products, no detailed frequent charging and discharging will damage battery life etc.

[0003] In addition, from the perspective of power system dispatching and operation requirements, the current vehicle-network interaction scenarios are mostly limited to orderly charging, demand-side response, etc.

However, under the guidance of the national "dual carbon" strategic goal, the intermittence and volatility brought about by the large-scale new energy access to the power system have greatly weakened the flexible adjustment capability of the power system. , the power system may face the dilemma of insufficient control resources
