Design, Control and Monitoring of an Offline Mobile Battery Energy Storage System for a Typical Malaysian Household Load Using PLC

Abstract

Battery energy storage system (BESS) is used in many practical applications including uninterruptible power supplies (UPS), portable devices, electrical vehicles and renewable energy systems. To utilize BESS effectively, an efficient control operation is required. Various controllers have been introduced in the open literature. However, they are not considered the best fit due to their limitations. This includes their incapability of handling high-power rating BESS, low noise immunity, short life cycle and limited number of input and output interfaces. In this paper, the programmable logic controller (PLC) is used to control and monitor a 158.8 kWh offline BESS for a typical Malaysian household. TIA Portal V13 software by siemens is used to program the proposed PLC control. Human machine interface(HMI) system is used to monitor and simulate the control performance. The results show that the PLC approach provides an efficient and reliable control of the BESS in which a compact protection against the battery overcharging, under-discharging and overheating is achieved.

Automatic control of the sand granulation process to improve homogeneity in the manufacture of ceramic tiles

“…In relation to the definitional objectives to be determined as part of the research, the discussions in relation to the results obtained are detailed. In the first place, it was found that under the control strategy proposed and implemented in the sand granulation process, it was possible to improve the percentage of humidity, which consequently will improve the homogeneity in the manufacture of ceramic tiles, this percentage improvement turned out to be 94.78%; In this regard, in the research carried out by [38], in which it specifies that through an automated system it manages to improve the quality of the sand granulation process by 55.75%, in this aspect it is from a point of view that it is a fact that industrial automation improves various aspects in a process, however, what is relevant and outstanding is to what extent the improvement is made, and in this aspect the strategy used is highly significant and contributes much to improving the quality of the manufacturing process of ceramic tiles.…”

Automating the mixing and spraying stage of the instant mashed potato process

“…In addition, automation is taken as a security control measure for jobs that are considered high risk, thereby protecting the integrity of the working personnel, minimizing the danger and reducing the risk of an accident. Authors in [38]- [43] are indicating that automation processes in industry 4.0 provide greater speed and productivity in food processes. Using three PLCs that communicate via Profibus using the Master-Slave protocol, greater efficiency has been achieved in the filling, dosing, packaging and transport processes.…”

Techno-Economic Assessment of On-Farm Anaerobic Digestion System Using Attached-Biofilm Reactor in the Dairy Industry

“…Furthermore, it was also shown that GAC is a suitable support carrier for the cultivation of microorganisms in biogas production. Biofilms formed on the surface of GAC were stable, and they provided an environment that was rich in nutrients that favored the microbes [28]. When fitted into the modified Gompertz equation, it was found that the highest biogas production A = 934.54 mL/gVS, maximum biogas production rate U = 60.55 mL/gVS.day, and lastly lag phase λ =1.04 days.…”
