Charging and discharging automatic demand response optimization method for electric car

Abstract

The invention discloses a charging and discharging automatic demand response optimization method for an electric car, and the method comprises the following steps: S1, obtaining the state information of the electric car connected in a power distribution network; S2, constructing an SDCO-ADR optimization configuration; S3, obtaining an initial charging and discharging plan (shown in the description), which can bring the biggest benefit to a user, based on the demand side optimization of PSDR; S4, obtaining an optimal charging and discharging plan (shown in the description), which enables the load fluctuation variance of the power distribution network to be minimum, based on supply side optimization of IBDR; S5, constructing an SDCO-ADR optimization configuration, and building a CVaR model of a client response intention decision. The method automatically carries out fine resource configuration according to the demand signal of a power company side and the condition of a user side, achieves the coordinative optimization of the supply and demand sides, and irons out the defects that manual response is low in efficiency, poor in reliability, strong in nondeterminacy and easy to cause response fatigue.

Description

Technical field [0001] The invention relates to an automatic demand response optimization method for charging and discharging electric vehicles. Background technique [0002] As the global primary energy consumption is exhausted and environmental problems become increasingly severe, the traditional energy grid structure is in urgent need of transformation. In the modern power system supply-demand relationship that emphasizes interaction, demand response (DR) resources have been regarded as virtual generators connected to the system on the demand side, and they are an indispensable new type of distributed energy in the era of energy interconnection. [0003] The idea of ​​vehicletogrid (V2G) is proposed, which enables electric vehicles to participate in the "two-way interaction" of the power grid in the form of DR. Judging from the current situation, on the one hand, electric vehicles are being vigorously promoted by governments and the automobile industry due to their potential in...
