Global energy demand,which is largely based on fossil fuels,is expected to increase *** effort must be made to mitigate carbon emissions and climate change to ensure sustainable and clean *** recent years,the increasing share of renewable energy and energy-storage systems,the development of electric vehicles(EVs),promotion of energy efficiency and demand-side management(DSM)have become today’s solution *** microgrid(MG),which involves the interconnection of several generation and storage units capable of operating locally with or without connection to the power grid,is also a very useful emerging *** study allowed the experimental operation and performance analysis of a grid-connected photovoltaic(PV)/battery/EV MG hybrid system,which was used for maximizing PV self-consumption and DSM *** entire MG consisting of two subsystems(polycrystalline PV array of 2.16 kWp for Subsystem 1,monocrystalline PV system of 2.4 kWp for Subsystem 2,EV with lithium-ion battery capacity of 6.1 kWh)was installed under outdoor conditions at the University Institute of Technology in Mulhouse,France in August *** operation and behaviour of the system components,including the inverter,batteries and power grid,were analysed in both scenarios with and without EV *** results shows that the total cumulative energy injected into the grid during the entire system operating cycle is estimated to be 3466.82 and 5836.58 kWh for Subsystems 1 and 2,respect*** addition,the energy produced by Subsystem 2 during its lifetime and the emissions emitted are respectively estimated at 5597.65 kWh and 4.17 *** other results in terms of PV output power,energy yield,feed-in power and self-consumed energy were quantified and analysed in detail.

A non-linear optimal(H-infinity)control approach is proposed for the dynamic model of multi-degree-of-freedom(DOF)electro-hydraulic robotic *** of electro-hydraulic manipulators is a non-trivial problem because of their non-linear and multi-variable *** this study,the considered robotic system consists of a multi-link robotic manipulator that receives actuation from rotary electro-hydraulic *** article's approach relies first on approximate linearisation of the state-space model of the electro-hydraulic manipulator,according to first-order Taylor series expansion and the computation of the related Jacobian *** the approximately linearised model of the manipulator,a stabilising H-infinity feedback controller is *** compute the controller's gains,an algebraic Riccati equation is solved at each time-step of the control *** global stability properties of the control scheme are proven through Lyapunov *** proposed control method retains the advantages of typical optimal control,*** and accurate tracking of the reference setpoints under moderate variations of the control inputs.
