An assessment method of wind power receiving ability of system considering demand response

In this paper, an assessment method on wind power receiving ability was proposed, as well as a set of indices. Then a secure constraint economic dispatching (SCED) optimization model was built, considering three typical types of demand response (DR) models: shiftable load, interruptible load and bio-direction load. With the mentioned assessment method, the benefits of the demand response on wind power consuming were quantified by the indices, which were measured in an IEEE-39-bus system case using the SCED model. The results of simulation show that DR resources could increase the receivable amount of wind power for the system economically and that assessment method can represent the feasibility of a power system to receive wind power validly and directly. In addition, these results can also point out the weaknesses of the system for receiving wind power, offering valuable information to both system operators and investors.
