Security optimal power flow considering loading margin stability using hybrid FFA–PS assisted with brainstorming rules
چکیده انگلیسی


• A planning strategy based hybrid method using FFA and PS algorithm is proposed.
• A dynamic process search inspired from brainstorming process associated to FFA and PS is proposed.
• Three objective functions are considered: fuel cost, power loss, voltage deviation and system loadability.
• Robustness of the proposed strategy (FFA–PS) is tested and validated on IEEE 14-Bus and IEEE 30-Bus.
• An efficient strategy for installation of SVC compensator based voltage stability is proposed.

This paper presents a new power system planning strategy which combines firefly algorithm (FFA) with pattern search algorithm (PS). The purpose is minimizing total fuel cost, total power loss and reducing total voltage deviation, with the objective of enhancing the loading margin stability and consequently the power system security. A new interactive and simple mechanism, inspired in brainstorming process, is proposed that allows FFA and PS algorithms to explore new regions of the search space. In this study the Static VAR compensator (SVC) is modeled and integrated in an efficient location which is chosen considering the voltage stability index. The proposed algorithm is interactive and tries to optimize a set of control variables at the same time, namely, active power generations, voltage of generators, tap transformers, and the reactive power of shunt compensators to optimize three objective functions such as: fuel cost, total power loss and total voltage deviation. These variables are optimized using a flexible interactive and competitive search mechanism. The proposed planning strategy has been examined and applied to two practical test systems IEEE 14-Bus and IEEE 30-Bus. Simulation results confirm the effectiveness of this hybrid strategy for solving the security optimal power flow.
