The increasing development of large-scale offshore wind farms around the world has caused many new technical and economic challenges to emerge. The capital cost of the electrical network that supports a large offshore wind farm constitutes a significant proportion of the total cost of the wind farm. Thus. finding the …

Modern power systems require increased intelligence and flexibility in the control and optimization to ensure the capability of maintaining a generation-load balance. following serious disturbances. This issue is becoming more significant today due to the increasing number of microgrids (MGs). The MGs mostly use renewable energies in electrical power production …

Randomness of wind speed around a short-durationstable mean value is commonly referred to as short duration wind variation. This paper investigates the effect of substantial windbased capacity inclusion on optimal load dispatch. with the source wind susceptible to short duration variations. Analytical formulation of the economic load dispatch (ELD) problem …

The private power producers are increasing rapidly to meet rising load demand in domestic. commercial. and industrial sectors. In this scenario. the distributed generation systems (DGs) play an important role over fossil fuel generation. Among different distributed generation technologies such as fuel cell. wind power. and solar. the fuel-cell-based distributed …

In this study the geometrical optimization of monolithically integrated solar cells into serially connected solar modules is reported. Based on the experimental determination of electrodes0 sheet and intermittent contact resistances. the overall series resistance of individual solar cells and interconnected solar modules is calculated. Taking a constant photocurrent generation density …

This paper presents a 24 hour ahead microgrid power planning using the approach of unit commitment by dynamic programming. The studied system comprises twelve PVbased active generators with embedded storage and three micro gas turbines. Based on the prediction of the energy available from the PV generator. the storage availability. …

Decentralized electricity generation by renewable energy sources offer greater security of supply for consumers while respecting the environment. But the random nature of these sources requires us to develop sizing rules and use these systems to exploit them. This paper proposes an integrated PV wind hybrid system optimization model. which …

This paper presents a method to operate a grid connected hybrid system. The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. The PV array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to …

This paper proposes a method of modeling and simulation of photovoltaic arrays. The main objective is to find the parameters of the nonlinear I–V equation by adjusting the curve at three points: open circuit. maximum power. and short circuit. Given these three points. which are provided by all commercial array …
