Day-ahead Generation Scheduling Model Considering Demand Side Interaction Under Smart Grid Paradigm

Demand side has become significant interactive resources under smart grid framework.This paper established a generation scheduling model considering demand side interaction under smart grid paradigm which brought demand response into generation dispatching on account of the mechanism of supply and demand side.This model took both the diversity of power consumption mode and intention of choice into account.Load curve was predicted by principle of user response considering consumer psychology.The model calculated the optimal price and reserve which can minimize generating cost based on coordinating and optimizing the interrupted load reserve and generation reserve.The generation scheduling solution would be presented on basis of above-mentioned optimal price and reserve.The result of IEEE 24-bus system indicated this model can decrease the generating cost effectively.It demonstrates the scheme combined power side and demand side based on demand side interaction may conductive to the safety and economic operation in power system.
