Security and Reliability Criteria for Substation Planning and Design

What is it about?

This article describes the main security and reliability criteria for demand connection planning through substations. The objective is to provide the basic information on the technical design specifications and criteria, technical terms and equipment parameters for planning of demand side substations, in addition to the requirements of normal case (N), contingency cases (N-1). Additional criteria, that covering aspects of quality of supply which are often contained in the grid code, should be considered in conjunction with the security standards.
