Behavior decision method of interruptible load agent

Abstract

The invention provides a behavior decision method of an interruptible load agent. The method comprises the following steps that an interruptible load reports cost information and power utilization information to the interruptible load agent, and the interruptible load agent obtains a morrow load prediction curve; an optimal interruptible load starting-stopping plan is made; the optimal quotation of each period is searched by the adoption of the extreme value search algorithm; a dispatch and trading center carries out economic dispatch, and releases a dispatch plan; the interruptible load agent carries out interruptible load economic dispatch and releases a power interruption plan to the interruptible load. The behavior decision method of the interruptible load agent can provide an effective means for the interruptible load resource to participate in the electricity market, provide the basis for the quoted price of the interruptible load agent, reduce total operating cost of an electric system and improve the competitiveness and flexibility of the electricity market.

Description

technical field [0001] The invention belongs to the technical field of power system operation and power market, and in particular relates to a behavior decision-making method of an interruptible load agent. Background technique [0002] The deepening of the market mechanism and the open utilization of load-side resources are the inevitable direction of the future development of the power system. Interruptible loads are widely distributed and large in number, making it difficult to centrally control them. At the same time, the lack of corresponding compensation mechanisms in the power system makes it difficult to realize the potential of interruptible user response scheduling. For this reason, the use of agency bidding method not only shares the pressure of dispatching and trading center regulation, but also helps to tap the dispatchable potential of interruptible users, and the use of economic dispatch within the agent to achieve coordination among interruptible users is als...

AI Technical Summary

Problems solved by technology

[0003] The research and practice of large-capacity interruptible loads signing interruptible contracts with power supply companies to provide reserve capacity to the power system has been widely carried out abroad and in Taiwan, but this method cannot fully tap the interruptible potential of small and medium-capacity users. Difficult to participate in the competition in the electricity market, lack of flexibility and competitiveness

However, the relevant research on the participation of interruptible loads in the power market in the form of agents has not yet been carried out.
