An integrated OPF dispatching model with wind power and demand response for day-ahead markets

In the day-ahead dispatching of network-constrained electricity markets, renewable energy and distributed resourcesare dispatched together with conventional generation. The uncertainty and volatility associated torenewable resources represents a new paradigm to be faced for power system operation. Moreover, in various electricity markets there are mechanisms to allow the demand participation through demand response (DR) strategies. Under operational and economic restrictions, the operator each day, or even in intra-day markets, dispatchs an optimal power flow tofind a feasible state of operation. The operation decisions in power markets use an optimal power flow considering unit commitment to dispatch economically generation and DR resources under security restrictions. This paper constructs a model to include demand response in the optimal power flow under wind power uncertainty. The model is formulated as a mixed-integer linear quadratic problem and evaluated through Monte-Carlo simulations. A large number of scenarios around a trajectory bid captures the uncertainty in wind power forecasting. The proposedintegrated OPFmodel is tested on the standard IEEE 39-bus system
