“…In [70], the authors proposed a probabilistic method where the unit commitment problem would determine the optimal amount of spinning reserve (Contingency Reserve and Following Reserve) for different load levels based on the probability of having insufficient generation due to generator outages or load forecast errors. The method evaluated the load probability distribution and evaluated the risk involved with the current unit commitment using a capacity outage probability table by the convolution of the cumulative probability distributions.…”

This paper explores the utilization of demand response in the day-ahead operation of an isolated microgrid in the presence of wind units. The operation of the network with high penetration wind units (i.e. uncertainty of wind units) is modeled as a unit commitment problem. In addition, electrical power storage is modeled in a daily power curve to decrease the effect of uncertainty in the wind units. Due to avoiding large-scale complexities and the deeper study effect of demand-side management on operations, the considered network is regarded as an isolated microgrid. The demand-side management is studied as demand shifting. The simulation results and discussion show the flexibility and advantages of the proposed method.

“…If sufficient FRR is assigned in the system to restore the frequency to within a reasonable safety range after extended contingencies in the system, and if it is assumed that the system load remained the same in the one minute following the generator outage, the 1-min recovery frequency f rec can be calculated using Equation (6) [23]:…”

“…Because this unit has an extremely rapid response, effective power can be appropriately adjusted without delays, to retain the generation-consumption balance between the generator output and the system and maintain the system frequency within the rated frequency range. Therefore, the dispatching of FRR will be more flexible to minimize operating costs and enhance system reliability [3][4][5][6][7][8].…”

Taiwan's power system is isolated and not supported by other interconnected systems. Consequently, the system frequency immediately reflects changes in the system loads. Pumped storage units are crucial for controlling power frequency. These units provide main or auxiliary capacities, reducing the allocation of frequency-regulating reserve (FRR) and further reducing generation costs in system operations. Taiwan's Longmen Nuclear Power Plant is set to be converted for commercial operations, which will significantly alter the spinning reserves in the power system. Thus, this study proposes a safe and economic pumped storage unit dispatch strategy. This strategy is used to determine the optimal FRR capacity and 1-min recovery frequency in a generator failure occurrence at the Longmen Power Plant. In addition, this study considered transmission capacity constraints and conducted power flow analysis of the power systems in Northern, Central, and Southern Taiwan. The results indicated that, in the event of a failure at Longmen Power Plant, the proposed strategy can not only recover the system frequency to an acceptable range to prevent underfrequency load-shedding, but can also mitigate transmission line overloading.
