Energy Storage in PJM: Exploring Frequency Regulation Market ...
Executive Summary. To maintain reliability, the electric power grid needs to always balance electrical supply with demand. While grid operators pay close attention to forecasting load (i.e. demand) and scheduling generation (i.e. planning for dispatch of generation supply) ahead of time, there will be short-term errors in load forecasts or …
Evaluating peak-regulation capability for power grid with various ...
Based on (1a), (1b), we summarize that the factors of determining the peak-regulation capability of a power grid include: (1) the boundaries of dispatchable ranges of units; (2) the on–off states of slow-startup units; (3) the upward and downward reserve demands; (4) the peak and valley load of power grid, as shown in Fig. 1.The first three …
