Renewable energy sources are still not the predominant resource in sector, although certain developed countries they participate a significant share electricity generation. It is estimated that world consumption from renewable exceeds 20% at present and continues to grow. appear as an additional source of conventional electro-industry. The main reason for increasing investment exploitation rene...

Abstract The article analyzes the development trends for renewable energy sources in 2010-2021. growing use of global balance developed and developing countries was revealed. share production electricity 2021 determined. results presented form approaches to integration order replenish processes provision services are based on an extensive assessment scientific Russian foreign literature. Integr...

At present, energy represents a key element in the social and economic development of territory. This is particularly true for fragile territories that are not interconnected, such as small island states. As many Small Island Developing States (SIDS) worldwide, situation Comoros substantially based on fossil fuel imports. The socioeconomic this archipelago overwhelmingly dependent security from...

The International Renewable Energy Agency (IRENA) is an intergovernmental organisation dedicated to renewable energy. In accordance with its Statute, IRENA's objective is to "promote the widespread and increased adoption and the sustainable use of all forms of renewable energy". This concerns all forms of energy produced from renewable sources in a sustainable manner and includes bioenergy, geo...

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 ...

This paper presents a three-phase four-wire Shunt Active Filter that compensates power quality problems and can also interface renewable energy sources with the electric grid. The inverter stage of the active filter is based in a two-level four-leg inverter and its control is based in the Theory of Instantaneous Reactive Power (p-q Theory). The filter is capable of compensating power factor, un...

Some studies of renewable portfolio standards find that regulations increase generation costs; others find that reduced demand for nonrenewable energy sources lowers natural gas prices and that electricity prices follow. This paper presents reasoning for why these predictions can vary in the direction as well as in the magnitude of their effects. The driving factors are the relative elasticitie...
