Description

System and method for intermediating electric vehicle flexibility resource availability resource}

The present invention relates to an EV (Electric Vehicle ) flexible resource mediation technology, and more particularly, to an EV flexible resource mediation system connection without complex system connection between a plurality of electric vehicle charging operators and demand management operators (demand management operator, MSP (Mobility Service Provider) and CPO (Charge Point Operator)) can participate in DR (Demand Response) using electric vehicle charging, and charging consumers can receive a discount on charging rates.

Flexible resource recovery using electric vehicles is being implemented by utilizing V2G (Vehicle To Grid) technology, which utilizes batteries installed in electric vehicles as an energy storage system (ESS) and connects them to the power system. In particular, the government introduced the plus DR (Demand Response) system to replace some of the output control with flexible resources as a demand-side countermeasure against the increase in Jeju renewable energy output control.

The Plus DR (Demand Response) system is a demand response system in which the control amount is reduced and compensated by increasing electricity usage when expected to control the output of renewable generators due to exceeding the demand limit (DR operators are SMP (SYSTEM MARGINAL PRICE), (compensated with a renewable energy certificate).

Output control has been implemented since 2015 due to exceeding the demand limit for new and renewable power in Jeju.

* Number of output control by year: ‘15) 3 times → ‘16) 6 times → ‘17) 14 times → ‘18) 15 times → ‘19) 46 times

* Control amount by year (MWh): ‘15) 152 → ‘16) 252 → ‘17) 1,300 → ‘18) 1,366 → ‘19) 9,223

In the case of factories or public institutions, there is no major problem in participating in the Plus DR market if the existing DR system is used because the subject and capacity of Plus DR are constant, and it is similar to the existing DR system.

However, there are many things to consider in order to expand the scope to flexible resource utilization using electric vehicles.

The unit registered as a flexible resource on the power exchange is the customer number (unit of electricity meter). Therefore, a charge point operator (CPO) that owns the charger and pays the electric bill owns the flexible resource. However, it is the charging service provider (MSP: eMobility Service Provider) that gives discounts on charging rates to EV owners participating in Plus DR, and the EV owners who actually participate in Plus DR and increase demand are the owners of EVs who charge them. As such, in the flexible resource development project using electric vehicle charging, the owner of the resource and the subject participating in the system are different, and the interests are very complicated. That is, there is a disadvantage in that the ownership of the resource and the subject of execution are different.

In addition, the number of customers using public electric vehicle charging stations is unspecified. The entity in charge of all Plus DR-related affairs, such as registering Plus DR resources on the power exchange, bidding, and distributing settlement money, is the demand management business, but the demand management business has no connection with the unspecified majority of electric vehicle owners using public electric vehicle charging stations. There are limits to participating in the Plus DR market using electric vehicle charging power.

In order to participate in Plus DR using electric vehicle charging power, a demand management business operator must bid on the power exchange, provide information such as the name and time of the successful Plus DR charging station to the electric vehicle owner, and manage the increase in demand. To this end, the electric vehicle owner It is essential to connect with charging service providers that have as members. However, there are currently about 31 such charging service providers, and this is expected to increase further, making it very difficult for demand management service providers to systematically connect with such various charging service providers. In other words, there is no link between demand management operators and electric vehicle owners.

In addition, public chargers have very limited resources compared to the number of electric vehicles. Therefore, there is a risk of confusion due to the concentration of electric car owners' charging during the time zone for Plus DR at the charging station where Plus DR is implemented. In order to maximize the increase in demand without causing confusion due to the concentration of electric car owners, it is necessary to introduce charging reservation so that they can participate in Plus DR at the agreed place and time. By granting reservation approval from 16:00 the day before (D-1) to 08:00 on the same day (D-day), owners of electric vehicles do not have to wait for recharging or wander, and demand management businesses can operate chargers efficiently. This can maximize the increase in demand. In other words, reservation charging is required.

In addition, in order to induce the participation of electric vehicle owners during Plus DR hours, incentives must be provided to customers who charge during that time period, and the most effective method is to discount electric vehicle charging rates. To this end, a charging service provider should selectively apply a discounted rate to customers charging at a specific charging station and at a specific time, but such a function is not currently provided. That is, a rate discount function is required.

In addition, in order to provide more incentives to charging operators and electric vehicle owners participating in Plus DR, CBL (Customer Baseline, standard rate), which is the standard for calculating settlement payments, is calculated by charging station and time slot, and bidding is conducted at the charging station with the lowest CBL. it is necessary to do If participating in Plus DR without considering CBL, the performance settlement amount is lower than the amount provided for the discount of charging fee, which may cause damage to the business operator. That is, it is necessary to calculate CBL.
