Clouds moving at a high speed in front of the Sun can cause step changes in the output power of photovoltaic (PV) power plants, which can lead to voltage fluctuations and stability problems in the connected electricity networks. These effects can be reduced effectively by proper short-term cloud passing forecasting and suitable PV power plant output power control. This paper proposes a low-cost...

Many sites of high solar insolation in Australia are located far from major load centres, and it is likely that the siting of future solar power plants in Australia will necessitate extensive transmission infrastructure. The unique generation profile of solar electric plants limits the utilisation of dedicated transmission lines rated to the peak output of a plant. If a plant is oversized for a...

Quality, reliability, and durability are the key features of photovoltaic (PV) solar system design, production, operation. They considered when manufacturing every cell designing entire system. Achieving these ensures that PV performs satisfactorily offers years trouble-free operation, even in adverse conditions. In each cell, quality raw material should meet standards. The fulfillment manageme...

In recent years, installing photovoltaic (PV) systems has become a worldwide trend. The prediction of solar radiation is very important to PV systems for power generation. For the large power-plant installations, the power allocations and scheduling form PV systems becomes an important issue. This paper aims at estimating the GSR for different locations in Brazil. A total of 20 locations spread...

This paper presents modeling and control of a hybrid distributed energy sources including photovoltaic (PV), fuel cell (FC) and battery energy storage (BES) in a microgrid which provides both real and reactive power to support a utility grid using fuzzy sliding-mode control (FSMC). The overall configuration of the microgrid including dynamic models for the PV, FC, BES and its power electronic i...

The research focused on the experimental evaluation of Photovoltaic (PV) – green roofs under Mediterranean climate summer conditions. Two autochthonous plants, Gazania rigens and Sedum clavatum, were selected for the PV-green systems while a PV-gravel configuration was used as the reference roof. The above mentioned roofing systems were developed and tested at the University of Lleida, in Spain...

This paper proposes and assesses an integrated solution to monitor and diagnose photovoltaic (PV) solar modules based on a decentralized wireless sensor acquisition system. Both DC electrical variables and environmental data are collected at PV module level using low-cost and high-energy efficiency node sensors. Data is real-time processed locally and compared with expected PV module performanc...
