Micro-grids are bits of a power circulation organize that supply various loads, and incorporate distributed generation (DG) like: wind and solar generators. Optimal power flow (OPF) is considered with the goal of limiting either the power circulation misfortunes, or, the cost of influence drawn from the substation and provided by (DG) units. This paper analyzes two systems: a system with no transmission...
To satisfy the demand of electricity with efficiently is a challenging work to the developing country like Bangladesh. Moreover, the radical utilization of conventional energy forces the authority to think about the alternative source. Also, the energy system faces major problem being distributed the power in remote area from a centralized system. Seeing these complications, some solutions have been...
In this paper, a probabilistic production simulation (PPS) based on the equivalent energy and frequency function method is proposed to analyze the power supply reliability and the production cost of a wind-photovoltaic (PV) hybrid generation system. Compared with the wind power generation system that has the same installed capacity, the wind-PV hybrid generation system increases the value loss of...
In developing country like Malaysia, the demand for electricity is expected to rise with increasing urbanization and rapid industrialization. Currently energy production is mainly dependent on fossil fuel but in the near future fossil fuels will not be sustainable because of the depletion of existing reserves and their impact on the environment. Wave energy is an environmentally friendly and fastest...
As the main emitter of CO2, power sector is becoming the primary focus for carbon reduction. However, existing researches mainly focus on power generation side, for example, renewable energies and nuclear, the role grid plays is often ignored. This paper assesses carbon reduction impact of cross-region power transmission in China by establishing a multiregion Integrated Resource Strategic Planning...
Conventional NPV analysis often reveals that the price of electricity produced by solar energy technology is significantly higher than that produced by fossil fuel using power plants. In the context of Bangladesh, this difference becomes more marked because the government of Bangladesh subsidizes the grid electricity, offering it to consumers at a cost below the cost of production. As a result, any...
The electricity and transportation industries are the main sources of greenhouse gas emissions on Earth. Renewable energy, mainly wind and solar, can reduce emission from the electricity industry (mainly from power plants). Likewise, next-generation plug-in vehicles, which include plug-in hybrid electric vehicles (EVs) and EVs with vehicle-to-grid capability, referred to as “gridable vehicles” (GVs)...
This paper demonstrates that the incorporation of optimally-rated energy storage units and renewable generators into a remote microgrid, in conjunction with an optimal dispatching strategy, can result in substantial reduction in the microgrid lifetime cost and emission. The application of such a microgrid can be in the electrification of off-grid remote communities which, typically, heavily depend...
This paper demonstrates that optimal selection of renewable power generators and energy storage devices in a grid-connected micro-grid, in conjunction with an optimal dispatch strategy, can significantly reduce the micro-grid lifetime cost and emission. The paper presents a mathematical model and optimization algorithm to identify the optimal micro-grid configuration (in terms of the installed capacities...
