Abstract
This paper investigates the formulation of a State Space Model for a Capacitor Coupled Substation to facilitate power tapping and injection into an electrical transmission network. The primary objective is to establish a state space representation of the electrical system that can be used to simplify the modeling of complex multi-variable electrical circuits or systems. To achieve this, two equivalent circuits are developed: one for electrical power tapping and the other for electrical power injection into an electrical power transmission network. Typically employed for extracting power from high voltage transmission lines and converting it to medium voltage at the distribution level through coupling capacitors, Capacitor Coupled Substations can also be utilized for power injection from alternative electrical power sources, such as microgrids, with appropriate power flow control systems. Thus, the study develops generic state space matrices for both power tapping and injection scenarios. Overall, this research significantly contributes to the field of electrical engineering by providing valuable insights into the fundamental development of capacitor coupled substations state space system representation for electrical power tapping and significantly for electrical power injection into the electrical power transmission network. The findings hold relevance for further modeling and analysis of micro-grid embedded electricity systems.
