A large number of stand-alone power systems that are based on fossil fuel or renewable energy (RE) based, are installed all over Europe. Such systems, often comprising photovoltaics (PV) and/or diesel generators provide power to communities or technical installations, which do not have access to...

This article investigates the extent to which the value of solar electricity (that is, electricity generated by photovoltaics), a form of distributed generation, would be higher under a nodal pricing system as compared to a uniform pricing system. More specifically, solar radiation and...

This paper presents an active islanding detection technique suitable for current controlled inverters. The method is based on reducing the magnitude of the injected current periodically and monitoring the voltage at the point of common coupling (PCC). Under grid failure, the change in voltage at...

This analysis examines the use of state policy as a tool to support the development of distributed generation photovoltaic (PV) markets. The focus is on low-cost market opening policies instead of various forms of government subsidies aimed at reducing installation costs. The ideas tested in...

The Brazilian National Electrical Agency (ANEEL) proposed in 2019 that the costs for accessing the electricity grid should be shared among all consumers. This would do away with cross-subsidies where normal consumers without installed solar distributed generation (DG) units effectively cover the...

There are a range of policy frameworks and support mechanisms to promote the penetration of renewable energy technologies into the energy mix assembled by the governments and regulatory bodies around the world. The three dominant and most common support schemes that have also been implemented...
