Development of Fast Derivation Method of Revenue Distribution for Power Trading Support

Abstract

We are developing the power trading support system for judgement on making contract of negotiation transaction. About this system, fast derivation method of revenue distribution is developed. Calculation amount of deriving revenue is very large, because risk factors take a various value. Revenue is derived using “cost function” which represents the price against the amount of electricity generation. The total number is same as combination of risk factors. So in developed method, risk factors are considered sequentially in calculation, and temporary cost function is assembled on each step. We evaluated the trade-off of between effect of acceleration and error amount by example. We got the prospects that cumulative probability error is within 2% and calculation time is within 1 minute.
