Grid Code, Part 2: Electrical Parameterization and Global Comparison in the Energy Sector

In this paper, the requirements, correlations, trends and global comparisons of the topic of Grid Code in energy systems are presented. The Grid Codes or guidelines for electrical systems began to appear in a general way more than 20 years ago around the world, among the grid codes of different countries there are certain common specifications, where they formulate the technical and operational characteristics of the different parties involved; namely, from the generation, transmission, and distribution of electrical energy to guarantee the level of quality of the energy supply that must be delivered to end users. There are many rules and policies in each Grid Code that deal with the process involved in the electrical system, establishing a series of requirements to facilitate flexibility and operational stability, security, and quality of the electrical energy supply. The concept of Grid Code is conceptually described as a technical document that contains the rules that govern the operation, maintenance, and development of the electrical system. This paper shows the typical requirements based on the parameters considered in different regions of the world to have a reliable electrical system in each country under the argument that the systems must comply with the Rule Books. The intention of this work is to show the trends in some countries where Rule Books for Grid Code are applied and compliance with the parameters used globally.
