“…In such architecture, open communication protocols like OPC contribute to overcome the limitations of contemporary systems. In [37] and [47] a hydrogen-based labscale microgrid to test different control approaches and their influence on the plant efficiency is proposed. A central PLC receives all sensor signals and manages the actuators.…”

The Object Linking and Embedding for Process Control (OPC) interface provides an effective means to exchange data between automation-related entities, both hardware and software. Since its creation, it has been profusely used not only for industrial scenarios but also for other spheres, among which energy automation is an important scope. In order to portray the relevance of such protocol, this paper presents a survey of applications of OPC communication to manage systems integration in the context of energy automation.Palabras Clave: industrial communications, OPC, energy automation, Smart Grid, interoperability.

“…With reference to the technologies layer, mainly capabilities regarding the flexibility of specific technologies or residential applications are of interest. In addition to the above, hydrogen as a storage medium has received much attention in the last few years because of the flexibility it can provide [53,54]. Electrolyzers can provide wind/solar peak shaving by splitting water with renewable energy sources electricity and producing hydrogen.…”

An Exploration of the Three-Layer Model Including Stakeholders, Markets and Technologies for Assessments of Residential Smart Grids

In this paper, a framework is presented for the evaluation of smart grid environment which is called the three-layer model. This three-layer model comprises three specific categories, or ‘layers’, namely, the stakeholder, market and technologies layers. Each layer is defined and explored herein, using an extensive literature study regarding their key elements, their descriptions and an overview of the findings from the literature. The assumption behind this study is that a solid understanding of each of the three layers and their interrelations will help in more effective assessment of residential smart grid pilots in order to better design products and services and deploy smart grid technologies in networks. Based on our review, we conclude that, in many studies, social factors associated with smart grid pilots, such as markets, social acceptance, and end-user and stakeholder demands, are most commonly defined as uncertainties and are therefore considered separately from the technical aspects of smart grids. As such, it is recommended that, in future assessments, the stakeholder and market layers should be combined with the technologies layer so as to enhance interaction between these three layers, and to be able to better evaluate residential smart energy systems in a multidisciplinary context.

“…In literature, a number of studies have been done on the RPGs‐based microgrid system including the hydrogen as storage medium in system and simulation domains . Some of the studies are focused on the MH‐based hydrogen storage system in microgrid . These studies have brought out the technical challenges to implement the hydrogen storage system in microgrid.…”

Techno‐economic analysis of metal hydride‐based energy storage system in microgrid

Hydrogen can be a promising option as an energy storage medium in renewable power generator‐based microgrid. However, the technologies used for the hydrogen storage such as high pressure in gaseous form and solid storages can significantly affect the cost performance of the hydrogen‐based microgrid. In this study, a techno‐economic assessment for solid hydrogen storage (metal hydride [MH])‐based microgrid in Indian operating conditions has been carried out in terms of levelized cost of electricity (LCOE), net present cost, and avoided environmental emissions. In the present microgrid, excess photovoltaic (PV) generator electricity is used to generate hydrogen using the alkaline water electrolyzer (EL). This generated hydrogen is stored in the MH cylinder. The stored hydrogen is converted back into electricity by fuel cell (FC) in case of insufficiency of PV electricity. The sizing of the microgrid components such as PV, FC, EL, and hydrogen storage tank are obtained for given load profile using HOMER optimization tool. An attempt has been made for the cost evaluation of the solid and high‐pressure gaseous storages in the microgrid. A comparative study between two energy storage mediums such as battery and hydrogen in microgrid is also performed. In case of battery and hydrogen storages, the LCOE is found to be 0.1293 and 0.383 $/kWh, respectively. It was found that battery storage system is more economical than hydrogen storage in microgrid. Nonetheless, the difference between the LCOE in hydrogen‐based microgrid is reduced considerably with optimized cost scenario of the EL, FC, and H2 storage tank as compared to the battery storage. Such technical, economic, and environmental assessment of the MH‐based microgrid system provides a firm basis to policymakers for shaping energy and environment policies for hydrogen activities.
