Description: 优秀论论及对应源码。电力系统配电网的无功优化规划是保证配电网安全、经济运行的一项有效手段，是降低网损、提高电压质量的重要措施。因此，电力系统配电网无功优化规划问题的研究，既具有理论意义，又具有工程实际应用价值。配电系统最优规划问题是一个复杂的非线性组合优化问题，至今未得到很好的解决。Tabu搜索(TS—Tabu search)算法是近年来出现的用于求解组合优化问题的一种高效的启发式搜索技术。本文采用固定并联电容器作为研究对象对系统进行无功补偿，并利用智能优化方法得到使配电网损耗降低最大对应的最优节点解。并在补偿容量的邻域搜索方面做了改进，采用扩大邻域搜索范围以达到全局最优的效果。用IEEE的两个算例得出的计算结果证明了这种方法的可行性。-Excellent deals on the corresponding source code.

Description: Type-1 fuzzy sets theory was proposed to handle uncertainty in control systems. But some
cases showed some liabilities of Type-1 fuzzy sets when facing with unpredictable
disturbance and uncertainties. Therefore Type-2 fuzzy sets was introduced and extended
while providing more degrees of freedom in designing criteria. The most important
specification of Type-2 fuzzy sets is the interval between a superior membership function
and an inferior membership function which is called footprint of uncertainty. This paper
presents a Bacterial Foraging Optimization approach for optimizing the parametrized
membership function. The above criterion is applied to an Automatic Voltage Regulator
system and results are presented and compared with previous method. -Type-1 fuzzy sets theory was proposed to handle uncertainty in control systems. But some

Description: The paper presents an in situ parameter estimation method to determine the equivalent circuit parameters of the three-winding
transformer (TWT). The suggested method also estimates geometrically a complex parameter that is mutual leakage between
secondary and tertiary windings, which would be useful in transient studies. Beside the saturation effect of the transformer is taken
into account by estimating a highly nonlinear parameter that is magnetizing circuit reactance. Different search based optimization
tools are applied for parameter estimation among which the results obtained using genetic algorithm is found to be encouraging.
Load test data at one particular operating point namely supply voltage, load currents, input power, and load impedance is suffi cient
to estimate the parameters. Platform: |

Description: This paper propose a Firefly algorithm (FA) for
optimal placement and sizing of distributed generation (DG) in
radial distribution system to minimize the total real power losses
and to improve the voltage profile. FA is a metaheuristic
algorithm which is inspired by the flashing behavior of fireflies.
The primary purpose of firefly’s flash is to act as a signal system
to attract other fireflies. Metaheuristic algorithms are widely
recognized as one of the most practical approaches for hard
optimization problems. The most attractive feature of a
metaheuristic is that its application requires no special
knowledge on the optimization problem. In this paper, IEEE 33-
bus distribution test system is used to show the effectiveness of
the FA. Comparison with Shuffled Frog Leaping Algorithm
(SFLA) is also given. Platform: |

Firstly, the layout of the main corridors in the planning area is determined to ensure the reservation of land resources. Then, on the basis of defining the purpose and principle of grid partition, the optimal partition of power supply grid in the global scope is realized based on the near selection of load standby substation and load clustering method. Finally, in each power supply grid, based on the classification of supply areas, the optimal wiring mode and reconstruction standards of primary and secondary construction are selected, and the main wiring planning is carried out.)
