An alternative approach for real-time balancing of electrical power systems

In this paper, we focus on the inefficiencies of current real-time balancing of power systems and propose an alternative solution. Our approach is based on the introduction of double-sided markets for the provision of secondary control and a market-based provision of primary control. We propose ancillary service (AS) markets for the provision of operating reserves, such that in real-time an optimal solution is reached for any considered power disturbance, without violating network constraints. We focus on a real-time control structure that enables consistent implementation/execution of AS contracts created in the forward markets for AS. We explain how these changes influence the current load frequency control implementation and which new commodities are to be defined to increase the efficiency and the reliability of the system. The presented real-time control structure is illustrated by linking its proposed functions with the currently existing solutions.
