In order to improve the adaptive control effect of the multiemergency power supply networking system connected to new energy (NE), this paper studies the adaptive control strategy (ACS) of the multiemergency power supply networking system connected to NE by combining intelligent algorithms and determines the appropriate installation node of the distributed power supply according to the voltage stability index. Moreover, this paper proposes a method to optimize the distribution network feeder reorganization and distributed power configuration problems based on the fireworks algorithm to reduce the network loss and improve the voltage distribution. In addition, distribution network reorganization and distributed power configuration optimization can more effectively minimize network losses and improve voltage distribution. Through the experimental research, it can be seen that the ACS of the multiemergency power supply network system connected to NE proposed in this paper has the established effect.

“…It is necessary to reconstruct the distribution network with distributed power generation. Literature [12] comprehensively considered the timing of load demand in the distribution network and the uncertainty of photovoltaic output and improved the photovoltaic power consumption through the optimization and reconstruction of the distribution network. In literature [13], the new three-dimensional group search method is applied to the configuration research of distributed power generation, and the purpose of reducing the system network loss is achieved by reconfiguring the distribution network.…”

In order to improve the intelligent distribution effect of the distribution network in the presence of distributed generation, this study combines intelligent algorithms to analyze the intelligent distribution of the distribution network in the presence of distributed generation. Moreover, this study establishes an objective function composed of system network loss expectation, voltage stability index, and reactive power compensation equipment investment. In addition, this study improves the artificial bee colony algorithm through tabu search algorithm and genetic algorithm and obtains an improved TS-IABC algorithm. Finally, this study compares and tests the performance of different algorithms in the form of functions and simulations. The simulation results show that the optimal intelligent distribution method of the distribution network in the presence of distributed power generation proposed in this study has a good effect and can promote the intelligent distribution of the distribution network.

In order to improve reliability of distributions, the neutrals are usually insulated or compensated with Peterson coil. Thus, the currents of single-phase to ground fault are weak, leading to difficulty in fault line selection problem. This paper investigates an evidence theory based integrated fault line selection method which employs multiple fault components to improve the performances of selection for neutral compensated distributions. Aim of this method is through the fusion strategy of the multi-fold unreliable fault components to arrive at more reliable solution. Three kinds of fault components including the transient, the abrupt changing, and the damped DC are developed. Fault measures are introduced for each line to quantitatively describe the likelihood of the line being the fault line. The fault components are extracted by dual-tree complex wavelet and atom decomposition. And the algorithms of calculating fault measures for the three components are developed according to the principle of the fault. The basic probability assignment (BPA) functions of evidence theory are established with the cloud model algorithm of data driven. Examples validate that through fusion algorithm of the multifold fault components, the line selection is more robust and reliable to varied circumstance than utilizing individual component.
