“…Literature [10] has required optimization of genetic algorithm method applied on the location and capacity of distributed power supply. Literature [11] optimizes the optimal configuration of DG, using fuzzy set logic theory, which has obvious effect of improving the voltage and line loss. Literature [12] establishes the line loss and profit model, price benefit model and environmental benefit model, based on the analysis of the distribution system with DG applied and used.…”

Interconnection of distributed generators (DG) has obvious impacts on line loss in distribution system and the effects depend on interconnected location, interconnected number and power injection of distributed generation. With discrete distribution model of constant power static load system accessing DG into consideration, establishes the line loss minimum as the objective function of the model and optimizes interconnected location, interconnected number and power injection of DG using a quantum inspired evolutionary algorithm. IEEE33 diffset results show that the application of the model and the quantum-inspired evolutionary algorithm can get reasonable DG interconnected location and power injection, effectively reduce the distribution system line loss.

“…Todas as técnicas analíticas revisadas usam necessariamente funções objetivo expressadas de forma algébrica e, a maioria delas, pretende apenas minimizar as perdas de potência. Algumas das abordagens analíticas incorporam lógica fuzzy [35], fatores de sensibilidade [36], análise de confiabilidade [37] As abordagens baseadas em LP apresentam boa convergência, podem trabalhar com grande variedade de restrições operacionais [39] e identificam rapidamente as inviabilidades produzidas nas tentativas de otimização. Mas as funções objetivo e restrições envolvidas no problema de otimização devem estar expressas em forma de equações lineares.…”

The insertion of distributed generation units in power grids is becoming an increasingly attractive alternative for electricity end users. This new scenario prepares utilities to meet these options, directly influencing the networks operation, control and planning under their concession areas.One of the multiple problems arising from distributed or decentralized generation is the proper allocation of distributed generators in electric grids. This research presents a new computational tool to address this issue that optimally and simultaneously allocates five photovoltaic distributed generation units in electric networks.'Optimal allocation' refers to the objective the proposed solution should achieve. In this case, this research aims to identify the buses of an electric distribution network where the injection of distributed electric power can minimize electrical losses.The proposed computational tool consists of an algorithm based on the metaheuristic optimization technique, Pattern Search, developed in MATLAB. The proposed algorithm connects with the Open Distribution System Simulator (OpenDSS) to run power flow and thus calculate the objective function (electrical losses).The author used a case study based on IEEE 123-Node Test Feeder to test the proposed solution performance. Loads in this network were modeled throughout the day using data from a São Paulo State concessionaire's field measurements, which the National Electric Energy Agency (ANEEL) makes available upon request. In addition, the author also included the solar radiance registered by São Paulo City weather stations.Results show the efficiency of the methodology developed in this research and indicate that applying it to different types of networks is possible.
