In the smart microgrid system, optimal sizing of battery energy storage system (BESS) considering virtual (VESS) can minimize cost and keep stable operation. This paper proposes a two-layer BESS strategy dispatch VESS in with high photovoltaic (PV) penetration. first layer, modelling aggregation are established, initial size is determined by participation demand response program. second studied...

a hybrid hydro/wind/photovoltaic base on hydrogen storage system is designed to supply power demand of pump stations. the aim of this design is minimization of net present cost of the hybrid system. optimization problem is subject to reliable supply of the demand. the system is investigated in the north west of iran (meshkinshahr) and the local data is applied. about 12 pump stations are found ...

as renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. this paper presents unit commitment (uc) which takes into account the volatility of wind power generation. the uc problem is solved with the forecasted intermittent wind pow...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

: In this paper, the operation of a future distribution network is discussed under the assumption of a multi-carrier microgrid (MCMG) concept. The new model considers a modern energy management technique in electricity and natural gas networks based on a novel demand side management (DSM) which the energy tariff for responsive loads are correlated to the energy input of the network and changes ...

This paper determines and compares the cost of energy (COE) of various hybrid systems for several off-grid facilities in North and Far North regions of Cameroon by integrating renewable sources and/or storage with diesel generators. The estimated annual energy production by solar PV systems and wind turbines is also discussed. The aim is to study the application of a high penetration renewable ...

In order to improve the availability of solar energy, this paper introduces a new solar energy storage device and its parameters automatic measuring system. The device puts the heat which was gathered by synchronous tracking solar collector into underground concrete storage pile. Meanwhile, the system could simultaneously measure the temperature, pressure and flow of the device, etc. Some deriv...

in this paper, plug-in fuel cell electric vehicle (pfcev) is considered with dual power sources including fuel cell (fc) and battery energy storage. in order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. in order to simulate the...
