This paper reports a solution to a relevant scientific task of determining the weight coefficients for an optimal system of automated control over the level of electric energy generation by renewable energy sources in a combined electric power system. It ... see more

Wind and solar PV have become the lowest-cost renewable alternatives and are expected to dominate the power supply matrix in many countries worldwide. However, wind and solar are inherently variable renewable energy sources (vRES) and their characteristic... see more

As a research result, characteristic indicators of the efficiency of using various heat sources in combined heat supply systems were determined. During the study, various schemes for integrating heat accumulators in heat supply systems were considered. Wa... see more

The Southern African Development Community (SADC) region has low energy security, exacerbated by electricity power cuts and load-shedding in almost all its member states. Green energy has the potential to contribute to the shortfall in the supply of energ... see more

The concept of ‘nearly zero energy buildings’ (nZEB) could represent a more sustainable aspiration within construction policies, although it has been a little analyzed approach in the Latin-American context. Currently there are different approaches in the... see more

The Southern African Development Community (SADC) region has low energy security, exacerbated by electricity power cuts and load-shedding in almost all its member states. Green energy has the potential to contribute to the shortfall in the supply of energ... see more

Incorporation of distributed energy resources (DERs) in power distribution networks makes the system combined and lively. Presence of DER with variable generating capacity at different locations converts protection coordination problem (PCP) to a very cha... see more

The value associated with an improved variable renewable energy (VRE) forecast has been quantified in this research. The value of improved VRE forecasts can increase with increasing VRE penetration levels as well as the range of this value becoming wider.... see more

 Summary: Photovoltaics is used for producing the electric energy from the solar radiation. These installations are becoming more and more popular. Their main advantage is the possibility of being mounted at any place without the significant interfer... see more
