DEMAND MANAGEMENT CONTROL METHOD AND APPARATUS FOR INDUCING DYNAMIC PARTICIPATION OF CONSUMERS IN ENERGY CONSUMPTION LOADS MANAGEMENT PROGRAM} for inducing dynamic participation of consumers in energy consumption load management program

The present invention relates to a demand management control method and a demand management control device for inducing dynamic participation of consumers in an energy consumption load management program, and more specifically, to distributed management of peak demand that places a burden on the power capacity of the energy supply system. For this purpose, the present invention relates to a device and method for inducing dynamic participation of consumers in a plurality of "energy supply and charging devices" in a distribution management area and remotely controlling them in real time.

In general, power systems must balance power supply and demand to make more rational use of limited electrical energy. Electrical energy requires a lot of investment on the supply side because the balance between supply and demand is sensitive at every moment. As peak loads occur according to power demand by time, the reliability of the power system must be secured to respond to peak loads. This will not relieve all the burden on the supplier side, but if managed in parallel on the consumer side, cost efficiency will greatly increase.

Accordingly, the power system requires various technologies to reduce peak-related supply facility investment demand. The power system performs demand management on the consumer side in parallel with stabilization operations measures on the supplier side. Here, Demand Management (DM) refers to a plan or activity in which the supplier side reasonably controls and adjusts the energy use pattern on the consumer side, and it is possible to solve reliability problems by adjusting the amount of usage according to the grid situation. .

Demand Response (DR) refers to the demand side's response to the supply side's management activities, and demand response systems can be divided into rate-based programs and incentive-based programs.

Rate-based demand response programs are subject to several limitations, such as securing the correct price signals and smart home appliances in order to apply the rate plan application time to the consumption site in detail according to the wholesale market price by time zone.

In addition, the incentive-based Demand Response program is a method of providing incentives for demand reduction performance when an event occurs to consumers who have previously participated in a demand reduction (DR) contract in order to maintain supply and demand balance. However, when suppressing consumption at such specific times, that is, reducing the load, the consumer's inconvenience must be taken into consideration. Additionally, consumption should not be simply suppressed to protect consumer rights and interests. Therefore, the demand management system has operating rules such as limits on cumulative time per year and limits on the duration of orders.

To expand the influence of dynamic control operations through demand response, a means of expanding demand response resource capacity that can manage load reduction is needed. In addition, a means of increasing the flexibility of demand response resource operation that reduces rigidity by improving load reduction operation constraints is also needed. Here, rigidity means restrictions on “resource response start time from load reduction announcement” and “load reduction application cumulative time.” If there is an opportunity to reflect consumption load characteristics in the demand response system, more flexible demand response resource capacity can be secured for system operation.

Figure 3 is a diagram illustrating the concept of the effect of distributing and managing peak load according to economic demand response according to an embodiment of the present invention.

Power consumption fluctuates over time, and energy facilities must be able to supply the power consumed by consumers. For example, ordinary residential distribution facilities are constructed with reference to the 3kW standard, and energy facilities for factories, buildings, and apartments are constructed with reference to the expected demand capacity. In addition, energy generation facilities are operated at the required capacity at each point in time, and energy supply facilities are configured to cut off power supply by judging it as overload when the allowable peak value is exceeded. A lot of investment is required to secure energy facilities. Accordingly, the allowable peak capacity of the energy supply and charging device is determined by considering the pre-calculated power usage.

Accordingly, the present invention can show an efficient method for distributing and managing the peak load by comparing the continuous consumption method and the discontinuous consumption method through the graph of FIG. 3.

The graph in (a) of FIG. 3 is a diagram showing the power consumption time compared to the allowable peak capacity of the energy supply and charging device according to the continuous consumption method. The continuous consumption method is a case in which charging requests from a plurality of charging load devices are concentrated in a specific time period, and it can be confirmed that the charging load of the charging load devices plugged into the energy supply charging device is generated. In addition, it can be confirmed that in the continuous consumption method, in addition to the general load generated during the charging process, a new facility allowable size is created as the capacity of the charging load is temporarily concentrated. Here, the new facility allowable size may represent an increased peak load due to load overlap in the form of an accumulation of charging load and general load.

Additionally, looking at the consumption time of the energy supply and charging device, in the continuous consumption method, when a charging load device is plugged into the energy supply and charging device, a continuous consumption peak occurs as soon as it is plugged. In addition, in the continuous consumption method, the charging load device is connected to the energy supply charging device even after charging of the charging load device is completed, resulting in a connection load or standby load.

On the other hand, the graph in (b) of FIG. 3 is a diagram showing the power consumption time compared to the allowable peak capacity of the energy supply and charging device according to the discontinuous consumption method. The discontinuous consumption method avoids specific time periods and is evenly distributed based on the charging reserve period of the charging load devices connected to the energy supply charging device. Even if the charging load of the charging load devices plugged into the energy supply charging device occurs, the peak load It can be confirmed that does not exceed the preset threshold. In addition, the discontinuous consumption method generates a charging load that does not exceed the maximum peak value by referring to the general load, so that demand can be distributed and managed within the consumer's energy supply target.

The present invention controls demand management for charging loads based on active participation orders from consumers based on a discontinuous charging method, allowing the energy supply side to directly control the consumption timing of remote loads. In addition, the present invention can secure the reliability of the energy supply and charging device at the distribution management area level by alleviating peak demand.

FIG. 4 is a diagram illustrating a connection relationship for controlling charging of a charging load device according to a charging type according to an embodiment of the present invention.

Referring to FIG. 4, when a participation order for a participation promotion based on the charging order form 106 is received, the demand management control device 101 controls charging at peak times according to the charging schedule of the charging load device 102 and energy The peak demand of supply and charging devices can be controlled. Here, the charging order form 106 may include a chargeable starting point, a chargeable period, current size, required capacity (total area), and an ID (socket outlet identification ID, in-cable box 501 identification ID) of the energy supply charging device. there is.

The demand management control device 101 may perform intermittent automatic demand management based on consumer participation orders. In other words, the demand management control device 101 may control charging of the charging load device 102 according to the charging schedule of the charging load device 102 based on the discontinuous consumption method. The demand management control device 101 may adjust the charging schedule by considering the properties of the plugged charging load device 102.

For example, the type of charging load device 102 is an AC slow charging electric vehicle, the charging infrastructure of the charging load device 102 is level 1, and the charging mode of the charging load device 102 is 'IEC Mode 2'. The charger connection method in (102) may be 'case B'. In the present invention, the type of energy supply charging device can be divided into “electric vehicle mobile charger”, “charging type portable charger”, or “charging type outlet charger”. Afterwards, the demand management control device 101 can issue instructions to the energy supply charging device and control charging of the charging load device 102 according to the charging mode ‘IEC Mode 2’, mainly targeting AC slow charging electric vehicles.

At this time, the “charging device for energy supply” may include a cable box 501 (in-cable-box). Here, the cable box 501 remotely controls and monitors whether the charging load device 102 is being charged, and may function as an earth leakage circuit breaker.

Figure 5 is a diagram illustrating the implementation effect and response of demand management contribution weights according to an embodiment of the present invention.

Referring to Figures 5 (a) and (b), the demand management control device 101 can secure spare capacity in the energy supply and charging device according to the consumer's order for participation in demand management. In other words, the demand management control device 101 can secure spare capacity of the energy supply and charging device by changing the consumption side through incentive weight response. The demand management control device 101 can increase the demand management effect by operating the demand management contribution weight of the charging load device to the energy cost.

The demand management control device 101 may provide a participation promotion to consumers who participate in the demand management program as an incentive for management contribution performance. In the present invention, the longer the ‘charging margin period’ included in the consumer’s charging order, the more advantageous it is to distribute consumption, and thus the incentive can be measured in proportion to the charging margin period. Accordingly, the demand management control device 101 may present a separate incentive to increase consumers' participating orders. Here, the charging margin period and incentive can be expressed as Equation 1 below.

As above, the demand management control device 101 induces the expansion of participants with variable incentives by presenting 'demand management contribution weight' on the supply side, and provides incentives and energy cost information to consumers to increase demand through promotion. It can lead to the expansion of management program participants.

Referring to (c) of FIG. 5, the demand management control device 101 may determine the demand management contribution weight to more efficiently operate the energy supply and charging devices in the distribution management area. The demand management contribution weight is a method of calculating the supply facility limit and peak load distribution value as the 'demand management contribution weight', and the 'supply facility spare capacity' according to the demand forecast value using big data on the operation records of energy supply and charging devices in the distribution management area. It can be divided into a method of calculating by learning the relationship between ' and 'demand management contribution weight'.

For example, as an example of the operation of an energy supply and charging device in a distribution management area, the present invention provides an electric vehicle (EV) charging point management operation system to alleviate the peak load on supply facilities in electricity management rooms of buildings, apartments, towns, etc. Available.

Looking at the graph in (c) of Figure 5, as consumption (x) increases, “supply facility spare capacity (y ₀ )” decreases, and “added spare capacity (y 0)” is reduced by operating the demand management contribution weight (D). y ₂ )” occurs, and it can be seen that the usable supply facility spare capacity (y _T ) increases. This can be expressed as Equation 2 below.

The demand management control device 101 compares the supply facility management cost value due to the spare capacity (y ₂ ) generated according to the operation of the demand management contribution weight and the incentive cost incurred by expanding the contribution weight, and determines the demand management contribution weight. The demand management control device 101 can calculate the contribution weight in a system for real-time rate operation and demand management and provide information to the supply facility operator to determine execution.

The demand management control device 101 can machine learn the ‘incentive weight’ operation results using previously secured energy demand and supply data to obtain the optimal operation value and provide it to the supply facility operator to determine execution. Additionally, the demand management control device 101 can utilize the response results to find an optimal negotiation plan between the consumer and the supplier.

Figure 6 is a flowchart illustrating the process of applying incentives by adjusting the demand management contribution weight according to an embodiment of the present invention.

In step 601, the demand management control device may set the demand management contribution weight of the charging load device related to the operation of the energy supply charging device. The demand management control device may set the demand management contribution weight using operating values previously measured from the energy supply charging device.

At step 602, the demand management control device may promote energy prices that include incentives. The demand management control device may receive a charging order for supplying power to a charging load device plugged into an energy supply charging device within the distribution management area. The demand management control device can secure demand response resource capacity for power operation that can be supplied from energy supply charging devices in the distribution management area based on the charging order. The demand management control device may provide a participation promotion that reflects the demand management contribution weight of the charging load device regarding the operation of the energy supply charging device.

In step 603, the demand management control device may determine whether charging is possible within the charging margin period of the charging load device according to the consumer's participation order.

If charging is possible within the charging margin period (Yes), in step 604, the demand management control device may supply energy to which incentives are applied to the charging load device.

If charging is not possible within the charging margin period (No), in step 605, the demand management control device may re-establish the capacity target of the demand response resource by the consumer's participation order.

In step 606, the demand management control device may determine the capacity target of the demand response resource and whether supply capacity has been secured.

If capacity is secured, in step 608, the demand management control device may adjust the demand management contribution weight to supply energy with reduced incentives to the charging load device.

If capacity is not secured, in step 607, the demand management control device may adjust the demand management contribution weight to supply energy that increases the incentive to the charging load device.

In addition, the present invention can be usefully utilized in terms of independence of microgrid networks. In detail, the existing power supply method was produced by a large-scale central power plant and transmitted at high voltage, but recently, there has been increasing interest in self-sufficiency through small-scale independent distributed power generation sources near consumers. In this case, stable supply and demand must be possible through independent production and storage of electricity.

Accordingly, in terms of strengthening the self-reliance of the energy cloud, the present invention can be applied in parallel to various energy supply and demand balancing means. This energy cloud contains internal energy production facilities and consumption loads, and is one of the means of reducing economic operating costs through a consumption-side approach. It is a real-time remote control demand management for the accumulated energy consumption load. You can use .

Here, in order to increase the operational independence of the energy cloud, the influence of ⓞ improving energy facility efficiency / ① securing energy sources / ② ESS charging and discharging / ③ load reduction (DR) through demand response must be increased. At this time, expanding the related facilities ⓞ, ①, and ② requires a large investment in facility expansion, but ③ can be an economical means of operation through peak load distribution without expanding supply facilities. Accordingly, the control capacity expansion proposed in the present invention can be used for self-reliance in microgrid operation.

In addition, the present invention can be used as a means of stabilizing the output of a power system including renewable energy and distributed power sources. In detail, the output supply characteristics of wind power and solar power generation, which are representative new renewable energies whose supply role is increasing in terms of reducing fossil fuel use, vary depending on the natural environment. Securing reliability can be said to be a challenge due to the intermittency of supply output. This is because it does not stably generate a certain amount of electricity every time, but is greatly influenced by the natural environment, resulting in uneven output. As renewable energy and distributed power sources increase, the power system is exposed to significant changes, requiring investment to ensure reliability.

Accordingly, in order to compensate for the intermittent output, it is necessary to secure and operate stabilizing and complementary facilities such as sufficient charging and discharging systems (ESS) according to the production capacity. Rather than relying solely on supply-oriented investment, there is also a plan to combine demand-side stabilization measures. There is also a growing economic demand to solve the reliability problem arising from the expansion of new and renewable energy from the consumer side rather than the supplier side.

Therefore, if the demand management technology that can flexibly link and reflect the fluctuating state of energy supply proposed in the present invention is applied, the investment cost on the supply side can be reduced proportionally.
