Hi Ambika, Following up what Ray suggested you might want to have a look at the IEEE RTS 96 test case (http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=780914). It includes a method for generating and hourly and yearly load profile for that case.

It seems you have energy amounts for solar generation and wish to create a power output that you can use in a power flow or optimal power flow model. For this you need to know the power profile of your solar generation (how it varies with time), then you need to know whether you want to simulate a peak power case or an average power case, or something else.

In that i need to size the solar generation. Also i am following the negative load approach. Power output of solar depends on the time of operation of PV array. So it may yield annual generation or daily generation. At each bus selected (In IEEE bus system) i have to subtract the solar generation from the load value. How to do this without knowing that the load at bus is daily or annual? kindly reply me from ambika ________________________________ From: Ray Zimmerman <[email protected]<mailto:[email protected]>> To: MATPOWER discussion forum <[email protected]<mailto:[email protected]>> Sent: Tuesday, 5 May 2015 11:52 PM Subject: Re: reg data i ieee In a power flow case, the load and generation values are steady state power values, not energy values. Daily or annual generation is energy.

In that bus data, the load at each bus refers to daily load or annual load. Also generation at each bus refers to daily or annual generation? kindly clarify my doubt from ambika ________________________________ The information in this e-mail may be confidential and subject to legal professional privilege and/or copyright.
