show that the proposed strategy can reduce the power flow
where FIRR is financial internal rate of return, CI is cash inflow, CO is cash outflow, –(CI − CO) t is net cash flow for period t, and n is project calculation period. When the financial internal rate of return is greater than or equal to the set discrimination benchmark i c (usually referred to as the benchmark internal rate of return), the project is financially feasible.
