Micro Grids are crucial for providing reliable and efficient energy services to a defined group, typically encompassing commercial or industrial facilities. These systems are composed of interconnected loads and distributed energy resources (DERs), all contained within clearly defined electrical boundaries.
Event Detail
The event was hosted by Dr. Fiaz Ahmad Chaudhry, Senior Advisor LUMS Energy Institute. In the event, a detailed presentation, on the topic, was given by Masroor Khan, CEO & Board Chairman at SB Electronics Engineering & Control (Pvt.) Ltd and was moderated by Hassan N Ansari CEng FIMechE, CEO Enterprise Excellence. The lecture was followed by Panel discussion and was participated by Dhanpat Kotak, Former CEO National Power Parks Management Company (NPPMC) Ltd and Nauman Ahmad Zaffar, Project Director National Incubation Centre LUMS.
Overview of Micro Grid Systems and Design Insights
Masroor Khan presented a detailed overview of the "Commercial & Industrial Micro Grids" event, beginning with the importance of designing load profiles tailored to specific venues and locations. He highlighted the use of Box Whisker charts by SBEE for determining distribution requirements throughout the year and introduced the concept of Heat maps to illustrate energy utilisation by the venues. He emphasised that the primary objective of a Micro Grid is to provide services to the grid while optimising Distributed Energy Resources (DER).
These systems are designed to manage load efficiently and ensure critical resilience. However, he acknowledged the challenges faced in system design, protection and automation, integration and operation, and maintaining resilience, particularly during black start situations.
To address these challenges, the concept of a digital twin was introduced, which aids in optimising the system and performing strategic analysis. Additionally, the event touched on the data exchange capabilities of Micro Grids through cloud options. The discussion also covered Long Duration Energy Storage (LDES) categories, including electrochemical, thermal, chemical, and mechanical storage.
Panel Insights on Benefits and Innovations in Micro Grid Technology
During the panel discussion, questions were raised about the differences between Micro Grids and National Grids and how consumers could benefit. The response highlighted that Micro Grids offer advantages like enabling Closed Transition Bypass Contactor (CTBC) and Business to Business (B2B) connections, digitizing the system, and reducing costs through strategic analysis. One panellist explained that Micro Grids have the potential to supply energy beyond basic subsistence levels, enabling the powering of productive loads. They also highlighted how Micro Grids can integrate and utilise various generation and storage sources effectively.
The panelist also discussed the potential for 24/7 solar generation, focusing on generating steam continuously rather than relying on solar energy for only 12-14 hours a day. They explained that by using storage containers with heating converter elements, solar energy could be stored during the day and then used at night to produce steam. This method extends the use of solar power beyond daylight hours, enabling continuous solar energy generation.
Impact and Future of Micro Grids
In conclusion, the Commercial and Industrial Micro Grid event plays a pivotal role in enhancing the understanding and application of Micro Grids among IMechE members globally. Micro Grids, with their ability to operate independently from national grids, offer a reliable and sustainable energy solution, particularly for commercial and industrial sectors.
As Micro Grids become increasingly essential in ensuring energy resilience and reducing carbon footprints, this event strengthens IMechE’s efforts in promoting sustainable engineering solutions. It also provides members with insights into cutting-edge trends, positioning them to lead in the global energy transition.
