description | A centralized reactive power compensation system
is proposed for low voltage (LV) distribution networks. It can be
connected with any bus which needs reactive power. The current
industry practice is to locally install reactive power compensation
system to maintain the local bus voltage and power factor. By
centralizing capacitor banks together, it can help to maintain
bus voltages and power factors as well as reduce the power
cable losses. Besides, the centralized reactive power system can be
easily expanded to meet any future load increase. A reasonably
sized centralized reactive power compensation system will be
capable of meeting the requirements of the network and the
optimization algorithm proposed in this paper can help to find
this optimal size by minimizing the expected total cost (ETCH).
Different load situations and their respective probabilities are
also considered in the proposed algorithm. The concept of the
centralized reactive power compensation system is applied to
a local shipyard power system to verify its effectiveness. The
results show that an optimally sized centralized reactive power
system exists and is capable of maintaining bus voltages as well
as reducing the power losses in the distribution network. A
significant power loss reduction can be obtained at the optimal
capacity of the centralized reactive power compensation system
in the case study. |
