HURWITZ LECTURE 1: Selling Random Wind

Abstract:

California is committed to reduce its GHG emissions by 90 percent by 2050. Meeting this goal will require de-carbonizing electricity using renewables. Wind (and solar) power is inherently random, but we are used to 100 percent reliable electricity service. Converting random wind into reliable electricity is expensive. Reserve generation must be available to compensate for wind power shortfall, but this increases emissions, and surplus wind power leads to negative prices and reduces the margins of fossil-fuel plant operators.

We propose an alternative. Let us package random wind power into electricity with different levels of reliability and sell them at different prices. Such an electricity market will reduce subsidies, and it is more efficient than the current market. However, we have to think of electricity service differently.

HURWITZ LECTURE 2: Measuring Traffic with Wireless Sensors

Abstract:

“If you cannot measure the traffic, don’t expect to control it.”

The literature on traffic management has many ingenious schemes to control signals at intersections and ramps, adapt tolls for countering congestion, improve parking through responsive pricing, and reduce crashes through vehicle-to-vehicle and vehicle-to-infrastructure communication. Virtually all these schemes are untested, because of a lack of adequate sensors to measure traffic.

We will describe the Sensys Networks wireless sensor platform for vehicle detection and its use for measuring vehicle flow, occupancy and speed, and estimating queue lengths and the travel time distribution. A test bed to measure the safety and efficiency of an intersection will be discussed. Lastly, two new sensing modalities will be presented: a weigh-in-motion system to estimate truck weight and a micro-radar sensor to measure bicycles, pedestrians, and parked vehicles.
