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 ...
Power generation capacity connected to the Malaysian National Grid is 22,858 megawatt, with a maximum demand of 17,788 megawatt as of April 2016 according to Suruhanjaya Tenaga. [7] The generation fuel mix in peninsular is 45.55% gas, 50.23% coal, 3.59% hydro and 0.63% from other forms of fuel.
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]
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 .
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...
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.
A LDC is similar to a load curve but the demand data is ordered in descending order of magnitude, rather than chronologically. The LDC curve shows the capacity utilization requirements for each increment of load.
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}}}}
