Description

Energy management system and method in a flexible energy community

[0001] The present invention relates to an energy management system and method in a flexible energy community.

[0002] Research related to this patent was conducted with the support of the Korea Institute of Energy Technology Evaluation and Planning (Research Project Name: Energy Demand Management Core Technology Development Project, Research Project Name: Development and Demonstration of Community Energy Management System (CEMS) for Demand-Based Energy Efficiency, Project Identification Number: 1415188030, Project Number: 00236325) under the supervision of the Ministry of Trade, Industry and Energy.

[0003] Electricity cannot be stored, and the supply and demand of electricity must be matched at every moment. However, due to the physical limitations of power facilities, there is a problem in that the supply of electricity cannot be flexibly increased in response to a rapid increase in energy usage.

[0004] Accordingly, various policies are being implemented worldwide to regulate energy demand by modifying building electricity rate systems. These methods include peak-linked basic rates, time-based differential rates, seasonal differential rates, late-night electricity rates, and demand-based selective rates.

[0005] Among these policies, the peak-rate base rate system, widely used to curb peak demand, is a rate system that encourages energy users to voluntarily curb their electricity demand by installing peak demand meters and charging a base rate based on the annual peak power consumption. In particular, the peak-rate base rate system is being utilized to reduce energy consumption in buildings by suppressing peak demand.

[0006] In the past, the Peak Cut control method, which temporarily cuts off the load to control the maximum demand power so that it does not exceed the target power, the Peak Shift control method, which controls power usage by changing the load usage time from the peak time to another time, and the peak control method using self-power generation facilities, which shares the load exceeding the target power with self-power generation facilities, were widely used as a method to control the maximum demand power. However, they only partially control the energy demand management of a single power user and have the limitation of not being able to optimally manage the energy demand management at the community level that includes multiple buildings.

[0007] Embodiments of the present invention aim to provide an energy management system and method in a flexible energy community to improve the energy efficiency of a flexible energy community by managing flexible energy according to the demand and supply conditions of the flexible energy community based on a multi-energy sharing grid topology.

[0008] However, the problem to be solved by the present invention is not limited to this, and may be expanded in various ways in environments that do not deviate from the spirit and scope of the present invention.

[0013] The above community energy management device can analyze energy efficiency including at least one of energy self-consumption rate, energy operation efficiency, and energy self-sufficiency rate through energy efficiency analysis of the monitored community resources.

[0014] The above community energy management device can improve energy operation efficiency through a demand flexibility method including at least one of a distributed resource method, a sector coupling method, an energy storage method, an unused energy utilization method, and a load adjustment method.

[0015] The above community energy management device can manage the sharing of energy resources and facilities between buildings in a flexible energy community or two-way energy trading between buildings according to the analyzed energy efficiency.

[0016] The above community energy management device can improve at least one of energy self-consumption rate, energy operation efficiency, and energy self-sufficiency rate by sharing energy facilities within the flexible energy community based on a multi-energy sharing grid.

[0017] Meanwhile, according to another embodiment of the present invention, an energy management method performed by an energy management system may be provided in a flexible energy community, the method including: a step in which a community agent interfaces with energy resources and facilities located in a building in a flexible energy community; a step in which the community agent collects energy data or transmits a control signal through the interface-based linkage; a step in which a community energy management device monitors community resources through linkage with the community agent; a step in which the community energy management device analyzes energy efficiency of the monitored community resources; and a step in which the community energy management device manages flexible energy according to the supply and demand conditions of the flexible energy community based on a multi-energy sharing grid topology using at least one of a distributed resource, a sector coupling facility, an energy supply facility, a common facility, and a sub-meter.

[0018] The above method may further include a step in which the integrated operation center integrates and operates a community energy management device corresponding to each community through linkage with the community energy management device and integrates and manages energy trading or sharing between different communities.

[0019] The step of linking based on the above interface may link energy resources and facilities including at least one of distributed resources, sector coupling facilities, energy supply facilities, common facilities, and sub-meters based on a predefined common interface.

[0020] The above method may further include a step in which the community agent monitors building energy resources based on internal network access to the building and operates in a building-independent model through the application of a web service accessible to the building manager.

[0021] The step of analyzing the energy efficiency may include analyzing energy efficiency including at least one of energy self-consumption rate, energy operation efficiency, and energy self-sufficiency rate through energy efficiency analysis of the monitored community resources.

[0022] The step of managing the above energy can improve energy operation efficiency through a demand flexibility method including at least one of a distributed resource method, a sector coupling method, an energy storage method, an unused energy utilization method, and a load adjustment method.

[0023] The step of managing the above energy can manage the sharing of energy resources and facilities between buildings in a flexible energy community or two-way energy trading between buildings according to the analyzed energy efficiency.

[0024] The step of managing the energy can improve at least one of the energy self-consumption rate, energy operation efficiency, and energy self-sufficiency rate by sharing energy facilities within the flexible energy community based on a multi-energy sharing grid.

[0041] FIG. 1 is a configuration diagram of an energy management system in a flexible energy community according to one embodiment of the present invention.

[0042] As illustrated in FIG. 1, an energy management system (100) in a flexible energy community according to one embodiment of the present invention includes a community agent (110), a community energy management device (120), and an integrated operation center (130). However, not all of the illustrated components are essential. The energy management system (100) in a flexible energy community may be implemented with more components than the illustrated components, or may be implemented with fewer components.

[0043] First, let's explain the Flexible Energy Community. A community can be defined as a collection of buildings with different energy consumption patterns, a group of consumers who adjust their demand and share energy to improve the community's energy efficiency. Residential and commercial buildings account for approximately 81% of the buildings in a community, making them a core component of the community. Furthermore, residential, commercial, educational, and healthcare facilities can be essential components for creating a sustainable community.

[0044] Therefore, the energy management system (100) in a flexible energy community according to one embodiment of the present invention can efficiently manage energy for a flexible energy community for demand-based energy efficiency targeting a community with essential building components such as residential, commercial, educational, and medical facilities.

[0045] An energy management system (100) in a flexible energy community according to one embodiment of the present invention enables flexible energy operation according to community energy demand and supply conditions based on a multi-energy sharing grid topology that utilizes various distributed resources, sector coupling facilities (e.g., P2H, P2G, P2M, etc.), energy supply facilities, and demand resources installed in each individual building and community of the flexible energy community. Through this, the energy management system (100) can improve energy efficiency in the flexible energy community.

[0046] An energy management system (100) in a flexible energy community can provide various energy services of a flexible energy community by considering the type and capacity of energy conversion facilities, infrastructure for sharing energy supply facilities and two-way trading (e.g., heat / gas, etc.) based on a multi-energy sharing grid topology.

[0047] An energy management system (100) in a flexible energy community can provide a long-term service model for energy circulation for existing and new buildings, a mid-term service model for existing buildings, and a short-term service model for responding to the auxiliary service market for new buildings, thereby efficiently operating a community for demand-based energy efficiency.

[0048] An energy management system (100) in a flexible energy community according to one embodiment of the present invention can optimize energy efficiency by linking with each regional unit (e.g., single-family home, multi-family home, public facility) platform through a multi-energy integration operation platform for energy integration such as heat or electricity.

[0049] An energy management system (100) in a flexible energy community according to one embodiment of the present invention can provide more economical, efficient, and diverse flexible energy services and support the creation of a successful flexible energy community.

[0050] Below, the specific configuration and operation of each component of the energy management system (100) in the flexible energy community of Fig. 1 will be described.

[0051] A community agent (110) may be composed of multiple community agents (110) in a flexible energy community, and each community agent (110) may be connected to each building in the flexible energy community. The community agent (110) may interface with energy resources and facilities located in buildings in the flexible energy community and collect energy data or transmit control signals to energy resources and facilities through interface-based linkage.

[0052] A community energy management device (120) can manage energy in a flexible energy community comprising multiple buildings. To this end, the community energy management device (120) is connected to a community agent (110) located in each building and monitors community resources through linkage with the community agent (110). In addition, the community energy management device (120) can analyze the energy efficiency of the monitored community resources. Through this, the community energy management device (120) can manage flexible energy according to the demand and supply conditions of the flexible energy community based on a multi-energy sharing grid topology using at least one of distributed resources, sector coupling facilities, energy supply facilities, common facilities, and sub-meters in the flexible energy community.

[0053] Meanwhile, the integrated operation center (130) may be linked to multiple community energy management devices (120).

In addition, the community agent (110) is connected to the sub-meter (115) through an DCU / GW (Data Concentration Unit / Gateway) (116) within the building through an interface linkage.

[0061] The community agent (110) may include an interface linkage configuration for metering energy supply facilities, sector coupling facilities, and demand resources within a building, linkage with a sector coupling operating system, and control of energy supply facilities and sector coupling facilities.

[0062] Meanwhile, the community agent (110) can be implemented as a building-independent system to manage energy in various facilities of the building.
