Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...

<p>Whale Optimization Algorithm (WOA) is a new meta-heuristic algorithm proposed by Australian scholar Mirjalili Seyedali in 2016 based on the feeding behavior of whales ocean. In response to disadvantages this algorithm, such as low solution accuracy, slow convergence speed and easy fall into local optimum, an improved Whale (IWOA) paper. We introduce chaotic mapping initialization keep ...

in this paper a new algorithm based on phasor measurements for estimating the thévenin equivalent (te) and system inertia constant is proposed. the method estimates the network te seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at phasor data concentrator (pdc) center. it is shown that the parameters of the te could be estimated at...

In this study, a particle swarm optimization with sigmoid increasing inertia weight (SIPSO) algorithm is proposed for structural damage identification based on the of vibration response constraints. view existing problems algorithms used identification, such as low accuracy and easy misjudgment location, introduced to improve global local search ability algorithm. Simulation results show that p...

A comfortable indoor environment contributes to a better quality of life and wellbeing for its occupants. The temperature, lighting, air are the main controlling factors user comfort levels. optimum control conditioners, ventilators helps in maximizing user’s level. Nonetheless, energy consumption these appliances needs be taken into consideration minimize operational cost at same time provide ...
