The feasibility and effectiveness of the proposed algorithm for optimal placement and sizing of capacitor banks in distribution systems, with the definition of a suitable control pattern, have been proved. 1. Introduction
The energy storage capacitor bank is commonly used in different fields like power electronics, battery enhancements, memory protection, power quality improvement, portable energy sources, high power actuators, ASDs, hybrid electric vehicles, high power actuators, off-peak energy storage, and military and aerospace applications.
Capacitor banks should reduce system energy loss, in addition to compensating for their lifecycle costs; otherwise, the capacitor placement is not economical. Load demand varies with time within a 24-h horizon as well as different days of the year.
The total cost consists of two factors, including the lifecycle cost of capacitors as well as the system's energy loss during the lifespan of capacitors. Thus, the capacitor banks should at least compensate for the lifecycle cost by decreasing the loss cost. The lifecycle cost includes installation, O&M, and purchasing (namely kVar) costs.
