Research on Power System Stochastic Economic Dispatch Considering Interruptible Load and Wind Power

Abstract:

Interruptible load was an important measure for demand response which can effectively implement the interaction between grid side and demand side. It’s also the important feature and component of smart grid. This paper established a stochastic economic dispatch model which brought both interruptible load and stochastic wind generation models into scheduling, and took the active and reactive power constraint of generator, the adjustable capacity constraint of interruptible load and the constraint of branch power flow into account. On the basis of Monte Carlo simulation and modified interior point method, a comprehensive optimization algorithm is proposed to tackle the above stochastic economic dispatch model. The result of IEEE 118-bus system illustrated that the proposed method can effectively curtail system’s operational cost and, to some extent, boost grid’s adaptability to wind power.
