Photovoltaic system Design

Because of global warming and the idea of further utilization of green energy as distributed generation or stand-alone systems such as solar and wind, installation of these power systems requires a pre-implementation of the project, which is important to its application. Here we did the study and simulation for installation of a 7.5 kW solar photovoltaic system by the AEG panel and the Delta Energy inverter. In this study, we can notice the energy generated at the beginning of the process as DC was 14.1 MWh. Seeing the losses of pannel, array and inverter for the system lead to 11.90 MWh energy by the solar power system added into the grid annually. solar photovoltaic panel data inverter data

Demand Side Management

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.

Photovoltaic System

As the world is going through growing in all aspects to better live by developing new technologies and a new standard of living, the people in a country will increase their use of energy to use that technology and that technology makes it easy to solve our problems until we get in trouble by facing with global warming and climate change or random events caused by nature.  Then, by the way, the source of energy we use is important.  We know that Renewables are the best solution as a reliable and free source of energy; photovoltaic systems produce electricity.  We designed a photovoltaic system and video shows the simulation and layout of that system in the project. Study of shading impact during a day (from 7 am to 4 pm) is the main target of this simulation.

HVAC system and TES

This is a preliminary design of thermal energy storage for an office building project by our team. You can see the chiller, AHU, cooling tower and thermal energy storage designed and placed on the roof of the building.  We represented the channels for air distribution and the piping system from the mechanical room from the basement of the building for heating purposes. By understanding the position for each equipment you can focus on the designation of a certain part of the system.

Energy Flow Chart

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.

What is Energy?

  Energy is something that we are using in our daily life on our planet earth to power our machines and bring comfort to our lives.  Electricity  and  Heat  are the most common  types of energy  that we are using in our homes.  we use electricity to turning lights on, washing clothes, playing video games, cooling ourselves in hot days of summer, having access to the internet, watching television and taking shower by cleaned and pumped water into our homes, etc. we also consume fuels to heat ourselves in winter and cold days.
