Climate change motivated by human activities constitutes one of the main challenges this century. To cut carbon emissions in order to mitigate carbon’s dangerous effects, current energy generation mix should be shifted renewable sources. The drawback these technologies is their intermittency, which will require storage systems fully integrated into mix, allowing them more controllable. In recen...

This paper introduces a new hybrid hill-climbing algorithm (HHC) for solving the Economic Dispatch (ED) problem. This algorithm solves the ED problems with a systematic search structure with a global search. It improves the results obtained from an evolutionary algorithm with local search and converges to the best possible solution that grabs the accuracy of the problem. The most important goal...

The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...

Hybrid renewable energy systems are expected to become competitive to conventional power generation systems in the near future and, thus, ptimization of their operation is of particular interest. In this work, a hybrid power generation system is studied consisting of the following main omponents: photovoltaic array (PV), electrolyser, metal hydride tanks, and proton exchange membrane fuel cells...
