The maximum demand charge is usually imposed on the peak power point of the monthly load profile, hence, shaving demand at peak times is of main concern for the aforesaid stakeholders. In this paper, we present an approach for peak shaving in a distribution grid using a battery energy storage.
Grid operators are charged not only by their total energy demand, but also by their highest power demand from the superior grid level. The maximum demand charge is usually imposed on the peak power point of the monthly load profile, hence, shaving demand at peak times is of main concern for the aforesaid stakeholders.
However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
Total daily heat load and average outdoor temperature. This paper proposes a distributed heating peak shaving system (DHPS), which integrates indirect solar flat plate collectors, electric thermal storage tank (ETST) and AHP, is retrofitted in parallel with a traditional heat exchange station to enable peak-shaving for heating, as shown in Fig. 5.
The process of reducing electrical power consumption during periods of high demand is called peak shaving. Utilities adapt the peak loads on the demand side with the end-users’ participation , , on the generation side (e.g., dispatchable power plants) and by grid upgrade measures , .
