At this time, there is a growing trend towards the introduction of renewable energy sources (RES) in Electric Power Systems (EPS), motivated by several reasons, among them, the growing environmental pollution and the extinction of fossil fuels. Cuba intends to change the energy matrix in the coming years (2025–2030) with a significant increase of these sources, mainly solar photovoltaic, which may reach a little more than 2000 MW installed by 2030. This imposes the need to develop studies that will make it possible to respond to a set of problems that accompany this decision: What measures are necessary to propitiate an acceptable behavior of the system frequency, taking into account the condition of isolated and weak system? How to use the experiences of developed countries to solve the drawbacks in frequency control in the face of a significant penetration of renewable sources, in particular solar photovoltaic? What model needs to be developed to carry out these studies? The main objective of this paper is to provide answers to these questions for Cuban Electric System scenario in the year 2030.

摘要

At this time, there is a growing trend towards the introduction of renewable energy sources (RES) in Electric Power Systems (EPS), motivated by several reasons, among them, the growing environmental pollution and the extinction of fossil fuels. Cuba intends to change the energy matrix in the coming years (2025–2030) with a significant increase of these sources, mainly solar photovoltaic, which may reach a little more than 2000 MW installed by 2030. This imposes the need to develop studies that will make it possible to respond to a set of problems that accompany this decision: What measures are necessary to propitiate an acceptable behavior of the system frequency, taking into account the condition of isolated and weak system? How to use the experiences of developed countries to solve the drawbacks in frequency control in the face of a significant penetration of renewable sources, in particular solar photovoltaic? What model needs to be developed to carry out these studies? The main objective of this paper is to provide answers to these questions for Cuban Electric System scenario in the year 2030.
