RT23 | Development of µController for Shore to Ship Power: Battery Energy Storage Controller CHIL

Shore to ship power technology has been an essential requirement for reducing the emissions of maritime transport at harbour areas, by implementing the clean renewable energy resources and using the state-of-the-art communication technology and standards. While environment and human health are posed in hazards by the gaseous emissions emanating from marine vessels' use of fossil fuel while they are berthed. Although shore to ship supply can be an affordable, sustainable, and emission-free solution and has already been implemented at certain seaports in several countries it is facing some technical and regulation problems. This research is aim to tackle solve some technical issues of the supervising, monitoring and controlling the harbour area smart grid by developing of a µController for Smart Grid battery energy Storage controller (BESC) for Vassa Harbor smart grid. Outline its development process, starting with the development of a preliminary controlling algorithm in C code, concluding with the design, and conducting of an IED (physical device controller) that complies with the IEC 61850 standard. This controller can maintain energy efficiently and shave peak load demand in harbour grids where transmission and distribution systems have a limited power capacity in such a way that mismatch of power supply and load demand is compensated by charging and discharging the battery energy storage system. Moreover, to test the effectiveness of the proposed control algorithm of battery energy storage system, a real data from the local distribution system operator Vaasan Sähköverkko and harbour operator Kvarken port of Vaasa has been implemented. The simulation results show that the designed BESC can balance power inside microgrid by charging and discharging of battery storage. The applied technique used in this paper is useful to validate the controller functionality in real time with the concept of digital twins’ simulation-in-loop (SIL), which is a practical approach, and it provides a cost-effective way to observe the performance of the controller.
