Risk Assessment of Micro Energy Grid Protection Layers
AbstractMicro energy grids (MEGs) are used extensively to meet the combined electricity, heating, and cooling energy demands for all types of customers. This paper develops a hazard matrix for a MEG and utilizes two advanced risk modeling approaches (fault tree and layer of protection analysis (LOPA)) for MEGs’ risk analysis. A number of independent protection layers (IPLs) have been proposed to achieve a resilient MEG, hence increasing its safety integrity level (SIL). IPLs are applied using co-generators and thermal energy storage (TES) techniques to minimize the hazards of system failure, increase efficiency, and minimize greenhouse gas emissions. The proposed modeling and risk assessment approach aims to design a resilient MEG, which can utilize those potentials efficiently. In addition, an energy risk analysis has been applied on each MEGs’ physical domains such as electrical, thermal, mechanical and chemical. The concurrent objectives achieve an increased resiliency, reduced emissions, and sustained economy. View Full-Text
