Hybridized System’s Categorization: Key Indicators and Distinguishing Characteristics

Activity: Talks and presentationsConference presentations

Description

Due to the variable and uncertain nature and low overloading capability of renewable resources (e.g. wind power, solar PV, etc.), interconnected utilization of these resources alongside other emerging technologies (energy storages, electrical vehicles, P2X, etc.) has been gaining more attention. This approach facilitates large renewable source penetrations and increases grid flexibility and market value benefits.
This integration has been shaped in different formats such as microgrids (MG), hybrid power plants (HPP), isolated hybrid power systems (IHPS), and hybrid energy plants . Comparatively, comprehensive research has been conducted about MG. Although these concepts are similar, there are certain distinctions in their nature and essence. However, the lack of a conclusive framework to distinguish these concepts has led to the interchangeable use of these terms, which can be misleading and confusing both for academia and industry. The main aim of this study is to achieve a better distinctive understanding of these hybridized systems.
MG is an electrical system aggregating the loads and distributed energy resources that can operate in grid-connected or islanded mode. IEEE 2030.7 Std. three peculiars for MGs which include i) clearly defined electrical boundaries, ii) a control system to present the MG as a single entity, iii) Installed generation capacity exceeding the critical load. According to this standard, the MG control system coordinates the operation of generators and demand response to present the MG as a single entity to the grid.
HPP is a power-generating plant converting prime energy sources into electricity. HPP consists of more than one technology (wind, solar, hydro, diesel generators, etc.) with or without energy storage . It is worth mentioning that the output of the power is electrical power which can be delivered to the bulk or islanded grid .
The isolated power system refers to the utility grids for remote areas or islands distant from the mainland such as the Faroe Islands, and Bornholm island . For instance, the Bornholm Island power system consists of several residential and commercial loads, steam units, combined heat and power, offshore wind power plants, etc. The system operator regulates the optimal power balancing between the different stakeholders to maintain the grid’s stability criteria.
It seems to be necessary to identify key indicators to distinguish between these systems. These key indicators are stakeholders, objectives, and structural attributes. The proposed presentation aims to discuss and compare these key indicators for the mentioned hybridized systems.
