I2Sim financial model and its application to UBC's living lab projects Ren, Rui
The Infrastructure Interdependencies Simulator (I2Sim) enables the user to explore the relationship and interdependencies among different infrastructures. Based on the same I2Sim ontology, and derived from a regular production cell, the I2Sim financial production cell (FPC) is designed to simulate and present the financial behaviors. UBC’s living lab model and living lab battery model provided an ideal testing ground for the I2Sim environment and its new financial production cell. In the living lab model, two of the financial production cells were integrated into the system, and provided with real time dynamic inputs. As expected, the financial production cell outputs correctly the cost of purchased resources as well as the ongoing real time costs. The results of this simulation successfully demonstrated the strength of the I2Sim environment and the capabilities of the financial production cell. In the living lab battery model simulation, two cases were tested. In the first test case, with demand peak-shaving as the main objective, an entire battery system model was developed from the ground up and finally integrated with the financial production cell. The simulation provided accurate financial analysis towards three different battery types: Flow batteries, lithium-ion batteries and sodium sulfur batteries. Although the results suggest that the battery system is not the most economical electric energy storage system at the moment, it again proved that the financial production cell is a suitable tool for many different business analysis cases. In the second case, delaying south transmission line’s upgrading process became the main objective; the test results showed that the flow battery was the best choice. The project was proven to be both technically and financially feasible.
