Special Protection Systems (SPS) are widely utilized for increasing power transfer in electric power transmission systems at the same time respecting security constraints. SPS applications usually are generation rejection schemes (GRS), line/transformer transfer tripping and load shedding. GRS are designed to mitigate overloading of a transmission line or lines after a power system credible contingency near the vicinity of a generating plant or are employed to arrest increasing dynamic oscillation which may lead to unstable system conditions by tripping electrical generator(s). Without the GRS, generation output is curtailed to satisfy the security criterion. With the GRS, the output of the generation is increased thereby increasing power transfer. In a nodal pricing based electricity market, curtailment of generation (without GRS), specifically of a cheap generation due to the security criterion can be considered as transmission congestion. Transmission capacity limitations impede the generation output thereby decreasing the profit opportunity of the generation company (GenCo). If a GRS is installed for this GenCo, the output of the GenCo is increased and thus there is a clear benefit for the GenCo in terms of profit. For the demand side, when generation output is curtailed due to congestion the resulting nodal prices at the demand’s location are higher than when a GRS is in place to increase generation output from a cheap generation. GRS installations have embedded cost and actual service cost. Since electricity market participants have various benefits in having a GRS installation, the cost of the service must be allocated among the beneficiary participants. Cooperative game theory is utilized in allocating fair cost on the beneficiaries of the SPS service. A modified PJM 5 bus test system is utilized as an example for the application of cooperative game theory in sharing the GRS service cost.
