Research on Discharging Price of Electric Vehicle Participating in Power Grid Dispatching Considering Reverse Cost

Abstract

As a controllable load and distributed energy storage unit, electric vehicle (EV) can use electric vehicle with vehicle-to-grid (V2G) technology to realize peak load shifting. In order to study the maximum bearing price of the grid in the discharge behaviour of electric vehicles, the paper takes the lowest operating cost of the grid as the objective function, establishes the optimal unit combination model of the standby unit during the peak load. The maximum bearing price of the gird is applied to the maximum cost of scheduling electric vehicle. Then the relationship between the maximum acceptable price and the power of the electric vehicle can be obtained. With the day-ahead load forecast, the upper limit of the electric vehicle acceptable discharge price is obtained. Finally, the simulation and analysis of the proposed method are carried out by numerical examples, and the feasibility and effectiveness of the proposed method are verified.

Flexible automatic detection for security management of dispatching data network

“…The emergence of the automatic power grid dispatching system has transformed the traditional manual management mode of power grid dispatching, into the information technologybased automatic management mode, which has improved the overall technical content and accuracy of power grid dispatching work [24,25]. The installation and deployment of power grid dispatching automation software platform is a novel upgrade to the traditional mode of power grid dispatching work, which is in line with the current construction and management requirements of the new power grid in China [26]. With the platform that deployed, the development goal of safe and stable operation of the basic electric power system can be achieved, and the economic benefits of grid operation can be improved.…”
