A Compact Review on the Impacts of Integration of Large-Scale Renewable Energy Sources into Grid-Connected Power Systems

Abstract

Consequent upon the inestimably magnificent rise in the necessity to considerably minimize the worrisome menace of global dependency on fossil fuels (such as coal, oil and gas), combat the pollution caused by green house gas emission emanating from same and lead a crusade against energy insecurity; the renewable energy sources (RES) became a panacea to the incessant imbalance between the ever- increasing demand and meagre supply of energy throughout the entire universe. Nevertheless, the output of RES is characterized with some unpleasant traits which include intermittency coupled with variability and unpredictability since it is largely constrained by annual weather pattern thereby inflicting a very severe injury on transient and steady state stability, reliability and profitability index. Thus, the certainty that this attributes do not only possess a gigantic capability to render synchronization futile but also initiate regular system collapse in the grid network cannot be over-emphasized, especially if the necessary precautionary measures are not taken into consideration. Therefore, this research work provides a compact review on the impacts of integration of large scale renewable energy sources into grid-connected power system. The methodology would involve an elucidative investigation of the associated benefits and obstacles after which possible mitigations to the challenges are accorded an extensive analysis while useful inferences are drawn meticulously leading to qualitative conclusions and useful recommendations from the results and findings so obtained.
