住宅分電盤電力計測データに基づくデマンドレスポンス効果の推定

抄録

The paper proposes a method to quantify the effect of critical peak pricing (CPP) Demand-Response (DR) for residential customers. The method uses electricity consumption measured at all circuits of a distribution board. Operation of appliances and rooms connected to each circuit and corresponding electricity consumption are first detected. By using the data, the baseline of electricity demand during DR period is estimated. The combination of the operation of circuits is defined as to be transition state modeled as Markov Chain. Then, electricity consumption is quantified by summing up electricity consumptions of all circuits corresponding to the estimated state. Due to the method, the DR effect can be distinguished into those due to the change in operation schedule of appliances and rooms and the change in the service-level provided by appliances and in rooms. This paper demonstrates the method by applying it to a DR experiment result.
