Análisis técnico, regulatorio y económico de la implementación de almacenamiento en baterías a gran escala en el sistema nacional interconectado : análisis económico de la implementación de almacenamiento en baterías a gran escala en el sistema nacional interconectado.

Abstract

The degree work presents a technical economic study of the implementation of battery energy storage systems within the national interconnected system (SNI). This storage can have different uses within the SNI such as frequency regulation, energy arbitration, voltage control, etc., where the economic study plays a fundamental role for the application of this technology and is what will be discussed in this work. In Chapter 1 you can find the description of the scope of the titling work as well as the general and specific objectives. In Chapter 2 contains the methodology with which the work was carried out. The types of studies carried out, the type of data analysis and the characteristics of the documents investigated from which a reference was taken to carry out the present curricular integration work are presented. In Chapter 3 numeral 3.1, a description of the development that energy storage systems have had over the years is made. In addition, you can find a classification and description of energy storage technologies with their corresponding applications. In Chapter 3 numeral 3.2, you can find a technological description of battery energy storage systems, in addition, the components that are immersed in BESS systems are described in a general way and a little description of some storage systems around the world. In Chapter 3 numeral 3.3, there is the study on the factors that can affect the feasibility of the implementation of the BESS systems taking into account the cost of the batteries with real and forecast values for a time of 5 years and the remuneration for the different services that BESS systems can provide. In Chapter 3 numeral 3.4, the financial economic study of the benefits of the implementation of the BESS systems in the SNI is presented, indicating the main advantages that can be had when investing in this system. In Chapter 3, numeral 3.5, business models for the implementation of energy storage systems are studied, where information is found about who can invest, who can buy these storage services and how the project investor is remunerated. considering different approaches explained in the corresponding chapter. In Chapter 3 numeral 3.6, with the information on the hourly marginal cost and the power reserved for the secondary frequency regulation, the calculation of the income that would be obtained if all the megawatts were dispatched was made, assuming that the frequency regulation would be satisfied by the BESS systems. In Chapter 4 you can find the recommendations and conclusions.
