The smart grid and micro-grid technologies are playing necessary role in power system due to their benefi ts over traditional utility grid system. In micro grid, control and management has many functions to keep up stability and to boost power quality of the system. In this paper, a hierarchical control is presented which incorporates primary, secondary and tertiary control levels are planned f...

With the rapid growth of thermostatically controlled loads, active power fluctuation and peak demand growth within an autonomous micro-grid become serious problems. This paper tries to suppress power fluctuation and shave peak demand for a micro-grid through optimizing domestic electric water heaters (controllable load). In this paper, domestic electric water heater models are first built to op...

A campus based smart micro grid model that combined power and heat is presented. In this study, optimal scheduling of distributed generations inside these smart micro grids is determined based on demand forecasting, solar power forecasting and wind power forecasting by artificial neural network (ANN). The proposed model is then evaluated through economical efficiency, environment efficiency and...

A switch-mode rectifier (SMR) can provide adjustable and well-regulated DC output voltage from the available AC source with good line drawn power quality. Depending on the input/output voltage transfer characteristics, the schematics, the operation quadrant, and control, SMRs possess many classifications and application. Typical potential application examples include grid powered motor drives, ...

This paper presents a mechanism for active power sharing among multiple dispatchable and distributed generation units within micro grid comprising one or interconnections with the main grid. Ideally, should act as constant load voltage source when connected to However, achieve ideal operation, natural variations intermittency of renewable energy sources microgrid need be adequately timely compe...

This paper implements models of two important distributed generators. The rst developed model describes and simulates the dynamic performance of a Single Shaft Micro Turbine, while the second model simulates the dynamic behavior of a Solid Oxide Fuel cell (SOFC). Increasing and reducing the power produced by these micro sources is also simulated. The two developed models can test the dynamic re...

Double-diffusion model is used to simulate slightly compressible fluid flow in periodic porous media as a macro-model in place of the original highly heterogeneous micro-model. In this paper, we formulate an adaptive two-grid numerical finite element discretization of the double-diffusion system and perform a comparison between the microand macro-model. Our numerical results show that the micro...
