Load Factor Improvement on Daily Load Curve Using Pump Storage
Making load factor approaching 1 will be used pump storage in the electric power system. The storage pump will act as a generator at peak load, thereby reducing the height of the peak load on the load curve. While at the baseload, pump storage will act as a motor load which serves to pump water from the lower reservoir to the upper reservoir
EIA''s Hourly Electric Grid Monitor provides timely data about
The U.S. Energy Information Administration''s (EIA) Hourly Electric Grid Monitor provides up-to-the-hour information showing electricity demand across the U.S. electric grid. Large-scale events that affect normal routines, from expected occurrences such as major holidays to unexpected situations such as the current COVID-19 pandemic, can change the pattern of
Pumped Hydroelectric Energy Storage as a Facilitator of
Energy storage systems have been recognized as a major facilitator of renewable energy, by providing additional operational flexibility. Through this simple concept, energy is transferred from the peak part of the daily load curve to the base, thus flattening the load curve. The first application of PHES dates back to the early 20th century

Second, it could allow a reshaping of the load curve beyond peak shaving to optimize generation cost (shifting demand from peak to base-load generation). And, revving charging up at times of excess solar and wind generation or throttling it down at moments of low renewables production could help to integrate a larger share of renewable power
Confronting the Duck Curve: How to Address Over-Generation of Solar Energy
Energy Department research is taming the duck curve by helping utilities better balance energy supply and demand on the grid. Solar coupled with storage technologies could alleviate, and possibly eliminate, the risk of over-generation. Curtailment isn''t necessary when excess energy can be stored for use during peak electricity demand.
As solar capacity grows, duck curves are getting deeper in California
The duck curve, however, has created opportunities for energy storage. The large-scale deployment of energy storage systems, such as batteries, allow some solar energy generated during the day to be stored and saved for later, after the sun sets. Storing some midday solar generation flattens the duck''s curve, and dispatching the stored solar
Electricity Demand and the Duck Curve
I''ve been playing with the "Duck Curve" for analyzing daily events, but there is a larger curve containing all the ducks of the year. Even presupposing that the daily ducks are flattened with storage and demand response, the larger "Duck Pond" curve shows an annual load curve that peaks at the middle of summer and in the dead of winter.

A coherent strategy for peak load shaving using energy storage systems
A comparison of daily load demand (baseline case) with daily shaved load due to BESS integration in case 1 and BESS with PV in case 2 is shown in Figs. 11 and 12, respectively. As can be seen, the load curves are flattened in the range of 9 MW by reducing the peak load and moving it to lower load times.
