Embodiment 1

[0093] As of February 2019, the number of electric vehicles in Shanghai has reached 250,000, so set N EV =250,000. It is assumed that only the home charging pile charging mode (that is, the distributed low-speed charging mode) is the potential flexible EV load. Non-flexible EV load refers to the load that car owners are unwilling or unable to participate in the peak-shaving demand response plan, assuming that such car owners start charging as soon as they get home (ie, disorderly charging mode). The maximum charging rate of electric vehicles is 7kw, and the charging efficiency is 90%. Assume that in the first calculation example, electric vehicles are not considered to participate in the peak-shaving demand response in the valley, but in the second calculation example, about 30% of the electric vehicles participate in the demand response to the peak-shaving valley.

[0094] The results show that, in case 1 does not consider the participation of electric vehicles in peak-shav...

Embodiment 2

[0099] It is estimated that by 2030, the total number of electric vehicles in Shanghai will reach 1.55 million under normal development conditions and 2.45 million under high-speed development conditions. This large-scale disorderly charging of electric vehicles will further increase the peak load of the receiving power grid on the one hand, but on the other hand, the potential demand response resources will also be more abundant. In order to further illustrate the feasibility and great potential of the present invention in the future, analysis and verification are carried out through a variety of examples of different numbers of electric vehicles. Assuming that the participation rate of peak shaving demand response is still 30%, the grid capacity and non-electric vehicle load remain unchanged. The results are shown in Table 2 and Table 3.

Abstract

The invention discloses an aggregator-based electric vehicle participation receiving-end power grid trough and peak regulation demand response regulation and control method. An aggregator issues a trough and peak regulation demand response invitation from a power grid operator to an electric vehicle, divides the trough and peak regulation demand response invitation into a flexible EV load and a non-flexible EV load according to a participation condition of an EV, and extracts a typical charging mode of the EV from historical charging data through a clustering analysis method for EV load prediction. And based on the load prediction data, the power grid operator establishes a rolling unit combination model considering participation of the electric vehicle in trough and peak regulation demandresponse, and determines a unit power generation plan and a demand response resource scheduling plan. According to the demand response regulation and control method, user willingness and a power griddemand are fully considered, interests of the two parties are effectively coordinated and maximized, and resource scheduling efficiency is improved through clustering analysis. The method can effectively stimulate the electric vehicle to actively participate in trough and peak regulation, reduces the trough and peak regulation pressure of the receiving-end power grid, and decreases operation costof the power grid.

Description

technical field [0001] The invention relates to the technical field of electric power system and automation thereof, in particular to an aggregator-based method for controlling demand response of electric vehicles to participate in peak-shaving in valleys of receiving-end power grids. Background technique [0002] The geographical distribution of my country's power resources and power demand are in a reverse trend from west to east. In the economically developed eastern region, the demand for electricity is high, but energy is relatively short, while the western region is rich in renewable energy such as hydropower and wind power. In order to solve the problem of unbalanced resources and demand, my country has vigorously developed the "West-to-East Power Transmission" project, which transmits the abundant power resources in the west to the receiving end power grid in the east through high-voltage direct current transmission lines. However, this measure has increased the prop...
