The effects of degree of freedom implementation for the operation of a BES providing PCR were analysed. Each degree of freedom was investigated individually and in combination with others to achieve common operation goals. An operational strategy exploiting the regulative degrees of freedom for a BES providing PCR was developed and described. In this strategy, a number of degrees of freedom are combined to facilitate SOC management. Since the utilization of the delay and system time correction degrees of freedom is not clearly stated in the regulation, two versions of the strategy, conservative and optimistic, were created. Simulations show that both versions of the strategy are able to reduce corrective energy use and energy cycling in the system (represented in full cycle equivalents), with this effect being much larger in the optimistic implementation. These effects could have important impacts in terms of operative cost reductions for the system.
