Integrated renewable energy and load management strategies in power systems

Abstract

The introduction of the renewable energy resources in the load management problem as part of smart grid initiatives requires further investigation and modifications to the load management formulation. In this regard, an innovative renewable energy storage scheme is introduced and investigated in this paper. In the approach followed in this paper, a portion of the demand energy is supplied from either solar panels or wind-driven energy schemes, which add to the green energy component of the load management scheme. The renewable energy-load management technology employed in this paper, while is being applied to the Hail bulk electricity area in Saudi Arabia, is general and can be applied quite as well to other bulk areas in the electricity system. The results for the application Scenario considered in this paper shows a maximum attainable annual profit of 14.7% can be achieved at off-peak valley filling designed capacity of 800 MWh with assumed energy reallocation efficiency of the load-management system of 50%.
