Abstract:
Aiming at the influence of demand response(DR) on load forecasting in the power grid planning, a highly operatable calculation method for the DR potential is proposed based on the DR characteristics including user adjustable ability and responsiveness. First, the general idea of DR potential evaluation is proposed for the power grid planning. Secondly, the fourquadrant method is used to analyze the important factors such as the adjustable ability and responsiveness that affect the DR potential, so that the key demand-side resources are determined in the near-term and future. Then, the peak-shaving and valleyfilling response potential evaluation methods of key demand-side resources participating in the incentive-based DR are proposed, which applies big data to the demand-side resources such as heating and cooling loads and industrial loads(e. g. the adjustable coefficient and customer directrix load). Finally, the future DR potential of a regional power grid is evaluated by the proposed method.
