What does it mean by the duck curve in electricity markets, what are its primary causes and what are two distinct challenges it poses for grid operators
Added by Christopher C.
Step 1
The duck curve is a graphical representation of electricity demand net of renewable energy generation, typically solar power, over the course of a day. It shows how net load (total demand minus renewable generation) changes, often resembling the silhouette of a Show more…

14. Application: Demand elasticity and agriculture The following graph illustrates the market for almonds. It plots the monthly supply of almonds and the monthly demand for almonds. Suppose a stretch of unseasonably good weather occurs, allowing almond growers to produce more almonds per hectare. Show the effect this shock has on the market for almonds by shifting the demand curve, supply curve, or both. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. A number of the growers are concerned about the price decrease initiated by the stretch of favorable weather conditions, as they believe it will lead to decreased revenue. Using elasticities, you will be able to determine whether this price change will lead to a rise or fall in total revenue in this market. Using the midpoint method, the price elasticity of demand for almonds between the price levels of $15 and $12 per ton is , meaning that between these two points, demand is . Thus, you can conclude that the grower's claim is , because total revenue will due to the favorable weather conditions.

what is a power curve of a solar cell and what does it represent?

Hydroelectric power is electric power generated by the force of moving water. Figure 1.15 shows $^{6}$ the annual percent growth in hydroelectric power consumption by the US industrial sector between 2004 and 2009 (a) Find the largest time interval over which the percentage growth in the US consumption of hydroelectric power was a decreasing function of time. Interpret what decreasing means, practically speaking, in this case. (b) Find the largest time interval over which the actual US consumption of hydroelectric power was a decreasing function of time. Interpret what decreasing means, practically speaking, in this case. FIGURE CANT COPY
