    This paper presents an alternative methodology, based on a cost optimization model, for evaluating some effects of the implementation of an alternative Demand Response (RD) program based on Day Ahead Real-Time Pricing (DA-RTP) in electricity markets. The proposed methodology has three special characteristics: the first one is to assume that users can modify their consumption patterns without altering the quantity demanded daily; second one, users flexibility to shift demand between hours depend of the kind of user and the time (peak vs off peak hours); finally, consumers have limited capability to shift demand outside of certain periods withing the day. The model is tested with a simulation exercise for the Colombian electricity market. The results show a significant improvement in system and market performance, including consumer savings, a flattened load curve, and reduced operational risk in the system. © 2003-2012 IEEE.

    Redes inteligentes y mecanismo de respuesta de la demanda: el caso del sector eléctrico colombiano Smart grids and demand response mechanism: the case of the Colombian electricity market ?
    (Universidad EAFIT, 2018-11) Garcia, John; Gutiérrez, Alejandro; Velasquez, Hermilson; Vargas, Luisa; jgarcia@eafit.edu.co
    Smart grids now figure prominently in the international debate on the design and regulation of electricity markets. This paper analyzes the potential effects of implementing a demand response mechanism in the Colombian wholesale electricity market with characteristics similar to that of the PJM market. Using time series models and controlling for the high volatility presented in the spot price, we estimate that such a mechanism could yield significant economic savings for customers. For example, if the demand response mechanism had been implemented during 2015, the spot price in peak hours would have been 30% lower and customers would have saved approximately COP $99.000 million.
