Firefly is Wayne State College''s system for faculty and staff leave requests, paycheck, and benefits information, set personal contact information, and travel requests. In Firefly, you can
In this paper, the diesel generator unit and fuel cell unit present in the standalone microgrid control the load frequency, the inputs of which are controlled by a Model Predictive Controller
A meta-heuristic firefly algorithm is used in Chaurasia et al. (2017) for finding the optimal controller gains of proportional integral (PI) and proportional integral derivative (PID) to
Grid Connect''s FireFly serial adapter features the same form, fit and function as older versions. Grid Connect, Inc. has introduced a new version of FireFly, a Bluetooth to RS232 serial adapter, as a replacement product for
The contributions of this paper can be summarized as follows: An effective and stable MPPT algorithm based on firefly algorithm modification is proposed. The mathematical modeling for the proposed scheme is introduced. The comparisons between the modified firefly algorithm and the conventional algorithms are executed.
According to the attractiveness level for the modified firefly algorithm, it has a different strategy compared with the primary firefly algorithm. The basic firefly algorithm suffers from that each firefly position is altered in a step-wise method to the more brightness firefly.
As clear from the figure, at t = 1.3 s, the P&O reaches the same duty ratio value as in the proposed algorithm. While for the firefly, it has unstable performance due to the lack of fireflies. But it can almost have near results to the proposed algorithm if the number of fireflies is increased.
It is based on tracking GMPP through a colony of fireflies. The proposed system performance is compared with traditional (P&O) and PSO (particle swarm optimization) techniques. The proposed technique achieved superior performance in terms of efficiency and speed than the two other algorithms.
At N = 3, there is an average output power enhancement by 5 Watt (201 Watt for modified and 196 Watt for firefly) for the modified firefly compared with the original firefly algorithm. As discussed above, with less number of fireflies, the primary firefly algorithm has high ripples.
The firefly can reach the MPP faster than the P&O algorithm. At G = 200 \ ( {W}/ {m^ {2}}\), the P&O algorithm needs 0.4 s to achieve the maximum power of 37 W.
