Abstract: An apparatus for estimating a fair value of a SPP includes a sunshine simulation system for generating a peak sun hour; a photovoltaic (PV) yield system for measuring a total power loss rate and generating an estimated energy-production-hours database; and a financial pricing system for generating a series of cash flows and discount factors. The financial pricing system computes a series of present values which are the product of the cash flows and the discount factors, and sums up all the present values to obtain an estimated value of the SPP. Since the apparatus for estimating SPP value takes the real power generation condition of the SPP and the real market economic condition into consideration, so that the apparatus can generate a pricing result even closer to the real market.

Abstract: A dynamic reference deviation detecting method is used for detecting a deviation of a dynamic reference coordinate system. A coordinate detecting step is for detecting and recording a first initial coordinate and a second initial coordinate. A first coordinate variation calculating step is for calculating a difference between a first instantaneous coordinate and the first initial coordinate to obtain a first difference value. A second coordinate variation calculating step is for calculating a difference between a second instantaneous coordinate and the second initial coordinate to obtain a second difference value. A relative coordinate variation calculating step is for obtaining a relative difference value. A dynamic reference deviation determining step is for determining whether or not the dynamic reference coordinate system is deviated according to the first difference value, the second difference value and the relative difference value.
