Sustainability enhancement is one of the optimization problems in the power system to improve system voltage stability and reduce system loss. Numerous well-known advantages of using capacitors in power systems include raising the maximum flow through cables and transformers, improving the system voltage profile and power factor, …
Generating reactive power in a power plant and delivering the load over long distances is not economically acceptable, but this reactive power is simply provided by capacitors or excited motors in the load centers.
