Technical and Economic Analysis of the Implementation of Battery Energy Storage Systems (BESS) for Nodes in the National Electric System (SEN) with High Concentration of Solar Energy

This document analyze the economic and technical impact of implementing storage systems in the northern region of the country on the Chilean electrical system, considering the national and international context where these emerging technologies are increasingly playing a greater role to enable a gradual transformation in the energy matrix of each country.To carry out this work, Plexos and Digsilent software will be used to implement case studies that replicate the operation of the Chilean Electrical System. Through the sofware Power Factory Digsilent (PFD), the Battery Energy Storage System (BESS) can be implemented, simulating the desired operational scenarios. Meanwhile, in softwares PLEXOS, the economic impact on the marginal cost and prices of the electrical nodes in the northern region with a high concentration of solar energy will be studied.
