The energy flow diagram is based on primary energy, secondary energy and the types of energy carriers. Types of primary energy are coming to power converting systems and then, go to end-user as electricity or refined fossil fuels. We made the model of the process in the picture above.
Demand-side management of electricity like the load shifting is a solution to reduce the capacity in the use of peak load power plants. Also, we can consider load shifting as demand-side resources by being a part of distributed resources. Here’s a design of a thermal energy storage system for a four-floor office building that was simulated by Trace700 software. We designed it to meet the 38% and 8% of the cooling load in two different scenarios. All the cooling load in 6 hrs of the peak on a day is 54%. It reduced the capacity of power plants in use and improved efficiency of the system.
When you decide to place a photovoltaic system to provide electricity and use clean energy sources as best as you can, first you need to take a look at the amount of radiation got to the ground and received by the pannels. So it is better to select an area of ground that receives much radiation and most of the time it happens in summer months when the sun is above our head and in the middle of the sky. Congratulations now you can choose a photovoltaic system and install it. But wait there is one more thing. Here you can see why we can not rely on solar radiation in a month of the year while it has the most and least energetic rays about to place a photovoltaic system or deciding on something else like water heating systems or thermal systems. So it has special analysis when you decide to install an efficient renewable working system.
