In a power system, a load curve or load profile is a chart illustrating the variation in demand/electrical load over a specific time. Generation companies use this information to plan how much power they will need to generate at any given time. A load duration curve is similar to a load curve. The information is the same but is presented in a ...
Maximum Demand Indicator (MDI) is an instrument for measuring the maximum amount [clarification needed] of electrical energy required by a specific consumer during a given period of time. [1] MDI instruments record the base load requirement of electrical energy .
Example: If a residence has equipment which could draw 6,000 W when all equipment was drawing a full load, drew a maximum of 3,000 W in a specified time, then the demand factor = 3,000 W / 6,000 W = 0.5 This quantity is relevant when trying to establish the amount of load for which a system should be rated.
Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.
At this time there is a combination of office, domestic demand and at some times of the year, the fall of darkness. [2] Some utilities will charge customers based on their individual peak demand. The highest demand during each month or even a single 15 to 30 minute period of highest use in the previous year may be used to calculate charges. [3]
Figure 3: This shows the utility maximisation problem with a minimum utility function. For a minimum function with goods that are perfect complements, the same steps cannot be taken to find the utility maximising bundle as it is a non differentiable function. Therefore, intuition must be used.
The standard newsvendor profit function is [] = [(,)] where is a random variable with probability distribution representing demand, each unit is sold for price and purchased for price , is the number of units stocked, and is the expectation operator.
Any Metering System where the average of the maximum monthly electrical demands in the three months of highest demand, either in: a. the previous twelve months; or b. the period since the most recent Significant Change of Demand (whichever is the shorter) exceeds 100kW.
