    Effects on Electricity Markets of a Demand Response Model Based on Day Ahead Real Time Prices: Application to the Colombian Case

    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.

    We analyze the main determinants of end user retail price according to characteristic of the Colombian electricity market, considering some key variables that determine the end user retail price. From the industrial organization approach, and using a panel data model, we analyze the influence of the vertical integration of the companies that participate in the electricity market on the regulated retail tariff, we control by network restrictions and by external factors such as the El Niño phenomenon. Based on the results found in the estimates, we propose a discussion on the current structure of the Colombian electricity market and a possible solution through prepaid electricity and smart meters that can provide better energy efficiency of the demand-side. © 2019 IEEE.
