  2. Maximum demand indicator - Wikipedia

    en.wikipedia.org/wiki/Maximum_demand_indicator

    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 .

  3. Supply and demand - Wikipedia

    en.wikipedia.org/wiki/Supply_and_demand

    If the demand decreases, then the opposite happens: a shift of the curve to the left. If the demand starts at D 2, and decreases to D 1, the equilibrium price will decrease, and the equilibrium quantity will also decrease. The quantity supplied at each price is the same as before the demand shift, reflecting the fact that the supply curve has ...

  4. Load profile - Wikipedia

    en.wikipedia.org/wiki/Load_Profile

    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 ...

  5. Market demand schedule - Wikipedia

    en.wikipedia.org/wiki/Market_demand_schedule

    At any given price, the corresponding value on the demand schedule is the sum of all consumers’ quantities demanded at that price. Generally, there is an inverse relationship between the price and the quantity demanded. [1] [2] The graphical representation of a demand schedule is called a demand curve. An example of a market demand schedule

  6. Demand - Wikipedia

    en.wikipedia.org/wiki/Demand

    [1] [2] In economics "demand" for a commodity is not the same thing as "desire" for it. It refers to both the desire to purchase and the ability to pay for a commodity. [2] Demand is always expressed in relation to a particular price and a particular time period since demand is a flow concept. Flow is any variable which is expressed per unit of ...

  7. Demand factor - Wikipedia

    en.wikipedia.org/wiki/Demand_factor

    The demand factor is always less than or equal to one. As the amount of demand is a time dependent quantity so is the demand factor. f Demand ( t ) = Demand Maximum possible demand {\displaystyle f_{\text{Demand}}(t)={\frac {\text{Demand}}{\text{Maximum possible demand}}}}

  8. Economic graph - Wikipedia

    en.wikipedia.org/wiki/Economic_graph

    The supply and demand model describes how prices vary as a result of a balance between product availability and demand. The graph depicts an increase (that is, right-shift) in demand from D 1 to D 2 along with the consequent increase in price and quantity required to reach a new equilibrium point on the supply curve (S).

  9. Demand curve - Wikipedia

    en.wikipedia.org/wiki/Demand_curve

    An example of a demand curve shifting. D1 and D2 are alternative positions of the demand curve, S is the supply curve, and P and Q are price and quantity respectively. The shift from D1 to D2 means an increase in demand with consequences for the other variables
