Microgrid systems located within commercial premises are becoming increasingly popular and their dynamic behavior is still uncharted territory in modern power networks. Improved understanding in design and operation is required for the electricity utility and building services design sectors. This paper evaluates the design requirements for a commercial building microgrid system to facilitate seamless mode transition considering an actual commercial building microgrid system. A dynamic simulation model of the proposed microgrid system is established (utilizing DIgSILENT Power Factory) to aid the development of planning and operational philosophy for the practical system. An economic operational criterion is developed for the microgrid …

Optimal Design Of Semi Active Control For Adjacent Buildings Connected By Mr Damper Based On Integrated Fuzzy Logic And Multi-Objective Genetic Algorithm, Mehmet Uz, Muhammad N. S Hadi
Faculty of Engineering and Information Sciences - Papers: Part A
An optimal design strategy based on genetic algorithms (GA) is proposed for nonlinear hysteretic control devices that prevent pounding damage and achieve the best results in seismic response mitigation of two adjacent structures. An integrated fuzzy controller is used in order to provide the interactive relationships between damper forces and input voltages for MR dampers based on the modified Bouc-Wen model. Furthermore, Linear Quadratic Regulator (LQR) and H2/LQG (Linear Quadratic Gaussian) controllers based on clipped voltage law (CVL) are also used to compare the results obtained by fuzzy controller. This study employs the main objectives of the optimal design that …
Investigating The Optimal Passive And Active Vibration Controls Of Adjacent Buildings Based On Performance Indices Using Genetic Algorithms, Muhammad N. S Hadi, Mehmet Uz
Investigating The Optimal Passive And Active Vibration Controls Of Adjacent Buildings Based On Performance Indices Using Genetic Algorithms, Muhammad N. S Hadi, Mehmet Uz
Faculty of Engineering and Information Sciences - Papers: Part A
This study proposes the optimal passive and active damper parameters for achieving the best results in seismic response mitigation of coupled buildings connected to each other by dampers. The optimisation to minimise the H2 and H- norms in the performance indices is carried out by genetic algorithms (GAs). The final passive and active damper parameters are checked for adjacent buildings connected to each other under El Centro NS 1940 and Kobe NS 1995 excitations. Using real coded GA in H- norm, the optimal controller gain is obtained by different combinations of the measurement as the feedback for designing the control …
