Description

Distributed Energy Resource-Based Distributed Resource Operating Apparatus and Method The embodiments of the present disclosure relate to a distributed energy resource-based power source operation apparatus and method. Energy storage devices are gaining increasing importance as a core component in next-generation power supply networks, such as distributed power sources and smart grid environments. Furthermore, with the recent active research on renewable energy sources like solar photovoltaic, solar thermal, wind, and bioenergy, they are also emerging as devices for storing this renewable energy. Although energy storage devices function as secondary batteries capable of repeated charging and discharging, their limited lifespan necessitates efficient scheduling of charging and discharging tailored to specific usage environments and purposes. In sectors connected to the power grid that supply power required by industrial or residential consumers, energy storage devices are used as an auxiliary means to schedule their charging and discharging based solely on the characteristics of time-of-day electricity rate differences. However, in terms of operation for supplying power connected to the power grid, there is a limitation in that the charging and discharging output of the Energy Storage System (ESS) cannot be scheduled to stably supply power to the grid by considering the internal physical characteristics of the energy storage device, which can ultimately lead to reliability issues in terms of power grid operation. Furthermore, as this technology primarily involves simply scheduling distributed resources from the consumer's perspective, such as for demand management and peak reduction, the development of technology for scheduling distributed energy resources to achieve dispatch resource status is currently minimal. FIG. 1 is a block diagram briefly illustrating a distributed energy resource-based power source operation device according to one embodiment of the present disclosure. FIG. 2 is a block diagram for explaining the data transmission and reception and operation of a power supply resource operation device according to one embodiment of the present disclosure. FIG. 3 is a diagram illustrating the updating of operation schedule result values at predetermined intervals according to one embodiment. FIG. 4 is a flowchart illustrating a distributed energy resource-based power source operation method according to one embodiment of the present disclosure. FIG. 5 is a flowchart for more specifically explaining step S430 according to one embodiment. In assigning reference numerals to the components of each drawing, the same components may have the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present disclosure, if it is determined that a detailed description of related known components or functions could obscure the essence of the present disclosure, such detailed description may be omitted. Where terms such as "comprising," "having," or "consisting of" are used in this specification, other parts may be added unless "only" is used. Where a component is expressed in the singular, it may include a plural unless otherwise explicitly stated. Additionally, terms such as first, second, A, B, (a), (b), etc., may be used to describe the components of the present disclosure. These terms are used merely to distinguish the components from other components, and the nature, order, sequence, or number of the components are not limited by such terms. In describing the positional relationship of components, where it is stated that two or more components are "connected," "combined," or "joined," it should be understood that while the two or more components may be directly "connected," "combined," or "joined," they may also be "connected," "combined," or "joined" with other components "intervened." Here, the other components may be included in one or more of the two or more components that are "connected," "combined," or "joined" with one another. In describing the temporal flow relationship regarding components, methods of operation, or methods of production, for example, when the temporal or sequential relationship is described using "after," "following," "next," or "before," it may include cases where the relationship is not continuous unless "immediately" or "directly" is used. Meanwhile, where numerical values or corresponding information regarding a component (e.g., levels, etc.) are mentioned, even without separate explicit notation, the numerical values or corresponding information may be interpreted as including a range of error that may occur due to various factors (e.g., process factors, internal or external shocks, noise, etc.). Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the attached drawings.
