The open shop scheduling problem involves a set of activities that should be run on a limited set of machines. The purpose of scheduling open shops problem is to provide a timetable for implementation of the entire operation so that the total execution time is reduced. The tasks scheduling problem in open shops is important in many applications due to the arbitrariness of the processing sequence of each job and lack of a prioritization of its operations. This is an NP-hard problem and obtaining an optimal solution to this problem requires a high time complexity. Therefore, heuristic techniques are used to solve these problems. In this paper, we investigate the tasks scheduling problem in open shops using the Bat Algorithm (BA) based on ColReuse and substitution meta-heuristic functions. The heuristic functions are designed to increase the rate of convergence to the optimal solution. To evaluate the performance of the proposed algorithm, standard open shop benchmarks were used. The results obtained in each benchmark are compared with those of the previous methods. Finally, after analyzing the results, it was found that the proposed BA had a better performance and was able to generate the best solution in all cases.

“…To verify the efficacy of the algorithm, the proposed HSE using DE method has been performed on five bus [29] and modified IEEE 14-bus system [30,31]. For both the systems, a delta connected SVC has been considered as a harmonic source whose current harmonic spectrum is given in [29] and [30], respectively.…”

In the present paper, a new approach to estimate the harmonic distortions is proposed by considering the existence of harmonic sources in the power system. The algorithm employs a differential evolution technique by formulating the reverse harmonic load flow problem for each harmonic order and by considering a limited number of phasor measurement units (PMUs) deployed across the power system. The technique utilizes the measured voltage and current harmonics obtained using synchronized PMUs with known transmission network as input data. The proposed technique estimates the harmonic voltage phasors at the unmonitored buses of the power system with reasonable accuracy. The effectiveness and efficiency of the proposed method is validated by applying it to five bus and IEEE 14-bus test systems by considering uncertainty in measurement noise. It is shown that the proposed approach yields optimum solution and provides reliable and accurate harmonic state estimates.

O Sistema Elétrico de Potência (SEP) está se tornando cada vez mais complexo e interligado, isso está relacionado a diversos fatores, como inserção de fontes renováveis de energia, aumento da demanda e desenvolvimento de novas tecnologia por exemplo. Dessa forma, um monitoramento, do SEP, mais eficaz e mais preciso é necessário. A PMU é um dos principais equipamentos da atualidade capaz de tornar o monitoramento do SEP mais preciso e eficiênte. Isso se dá pela sua taxa de amostragem superior das grandezas elétricas do SEP em relação aos medidores atuais e também na realização das medidas em formas fasoriais. O problema das PMUs está relacionado ao seu alto custo e a consideração da rede de comunicação entre a PMU e o PDC, desta forma, esse trabalho apresenta uma forma de alocação de PMUs e PDCs, com o objetivo de minimizar o custo de um sistema com PMUs e garantir um sistema totalmente monitorado. Para alcançar esse objetivo foi aplicada uma Programação Linear Inteira para os sistemas do IEEE de 14 e 30 barras.
