I am making a model of Electric vehicle load on electric grid. I was using formulas to calculates things but now what i need to do will not be possible with formulas. I have not worked with VBA before so have no idea how to do it. if someone can help, it will be great. I have attached a part of workbook not to make it complicated.
The code will use <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">IF</code> statement with multiple conditions and check if voltage drop is more than 5% (marked red) <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">OR</code> current if it is less than 0.6 (marked red). if anyone of the condition is <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">true</code> it will decrease the charging load of the car by 1kW e.g. from 11 to 10. This code will look every row and keep decreasing the load until both conditions are <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">false</code>. now as we decrease the charging load, the car will take longer to charge, so the more time cells will have load. numbers of cells for every load is calculated in the workbook, which can be used. when the load reaches 12 am it should also rotate and start from the top i.e 12:15 am. the results are printed in the output table as the input tables are calculated by formulas and cannot be disturbed.


Maybe its not hard but i dont have VBA knowledge to perform this task.
