Solar container peak-shaving policy risks

Does peak shaving reduce power peak?

Thus, any intent to reduce the maximum power peak can have an enormous benefit from an economic point of view, and peak shaving policies have been proposed. Peak shaving implies the lowering of the highest observed peak in energy demand to reduce the energy-related costs.

Are peak shaving policies effective in reducing power peak of QCs?

The results suggest that both peak shaving policies are effective in lowering power peak of QCs at container terminals with double cycling. Policy 2 (limiting maximal QCs' power demand) performs better in reducing the maximal power demand of all QCs ( Pmax) without compromising the productivity and utilization of QCs ( pQC, uQC ).

What is peak shaving policy?

In case of peak shaving policy is carried out, each QC needs to request permission from Main Agent before it starts a new movement. Main Agent looks at whether the request for new movement is permitted on the basis of peak shaving policy.

How does peak shaving affect the power output process of hydropower units?

Power output process of some hydropower units. Fig. 9illustrates the impact of peak shaving without energy storage on a sunny day. Due to the limitations imposed by the anti-peak shaving characteristics of wind and hydropower generation, the system struggles to track the load during the second peak period effectively.

Why is short-term peak shaving optimization important?

Short-term peak shaving optimization has become increasingly critical in modern power systems due to the rising penetration of renewable energy [17, 18]. The intermittent and non-dispatchable nature of wind and solar energy significantly increases the challenge of managing the abrupt changes in load demand.

How can QCs with double cycling improve peak shaving energy demand?

With the help of the established agent-based simulation model, the power demands of QCs at container terminals with double cycling can be visualized for new operation rules of peak shaving energy demand of QCs, and the values of evaluation indicators are also achieved for different scenarios of peak shaving policies.
