Renewable Systems Planning & Design

Renewable Systems Planning & Design

Our latest inclusion of renewable energy system & microgrid design engineering services brought Automize closer to becoming a fully integrated engineering company in the renewable energy domain. Now, we can provide a one-stop solution for renewable energy system analysis and design.

Our electrical engineers have worked on a wide range of solar projects all over the globe; solar farms ranging from 1 MWp to 333 MWp. Microgrid feasibility analysis from projects for C&I clients, islanded operation of the marijuana growing houses, universities, and hospitals. For microgrid developments, our engineers have completed pre-FEED techno-economic analysis where they have run different operational scenarios with investment at different renewable or alternative energy generation options and determined the best investment scenario with the least payback period. For such kind of analysis, our engineers use HOMER Pro and HOMER grid optimization software. The deployment of microgrids not only reduces the operational energy cost but also gives our clients independence and reliability against grid outages.  Universities and Hospitals prefer to have some degree of reliability in their power delivery options due to the nature of the load. Our engineers have a broad range of experience in designing and deploying residential and utility-scale solar farms.

Using PVsyst, Helioscope, and SAM software, they can find the optimal size of the solar system which would meet the clients’ requirements specifically. Moreover, our engineers are experienced enough to review the drawing and develop the local (US and Canada) compatible format of the electrical and civil design. Our electrical engineers have been involved in large-scale brown and greenfield solar farm development. All the applicable NEC, NESC, and CSA codes are reviewed and, in some cases, local conversion of the required codes has been done by our engineers.

How we do it better? We listen! We find customers need specific fit-for-purpose solutions. Our electrical engineers have an extensive academic background in renewable energy system design, microgrid development, load flow analysis in ETAP, transient analysis in PSCAD, and PSS-E simulation environments. They have worked in the world’s top-tiered solar farm developer companies as well as leading consulting engineering companies in North America and bring in decades worth of hands-on experience. That’s why when we work on a solution at the conceptual stage, we can foresee future issues during construction and commissioning.

Have you done a simulation model of your plant for energy optimization? Our electrical engineers can build techno-economic models in the industry-accepted energy system optimization, such as HOMER, RETScreen, SAM, and few others depending on the clients’ specific requirements. Techno-economic optimization on the mentioned software, give our clients a clear idea about different investment options and the pros and cons of each investment. Thus, before making an investment decision, our clients become aware of the different viable options and the best-returned option. When the project moves to the next design phase, our engineers’ decades-long experience in system design, power flow analysis, and good communication with different equipment vendors help the client complete the design phase efficiently as well as start the procurement phase at the same time.

During the construction phase, our engineers sometimes work as owners’ engineers and sometimes supervise and monitor the construction phase of the work. During the commissioning phase, our engineers actively work along with the vendors’ engineers and technicians to ensure the smooth operation and transition of the project.

Common renewable system planning and design services include

The service on the renewable energy system design can be divided into the following categories

Feasibility Analysis: Under this service, the feasibility (CapEx Requirements, O&M cost determination, Level 5 to 3 cost estimation, System Sizing, Payback period, and NPV) implementation of a renewable system is determined through detailed calculation. HOMER and in-house optimization software are used for this kind of analysis.

Energy Production Estimation: When a large-scale solar farm, wind farm, and microgrid system is planned to install. Detailed modeling work is required at the beginning to determine the guaranteed energy production over the lifetime of the project. PVSyst, SAM, PV Planner, and Helisocope are used for solar system modeling. WindPro is used wind system modeling.

Microgrid Modeling: When a microgrid is intended to implement as a grid-connected or standalone one, the energy balance and a careful system sizing of the different assets are required. This careful sizing of the different assets and steady-state energy balance is ensured through professional optimization work in HOMER, SAM, and RETScreen are used.

Power System Analysis: When the system sizing is done, based on the project requirement load flow and Short Circuit analysis are done on ETAP. ETAP is widely used software in the industry for this purpose.

Interconnection Study: When a renewable energy system or microgrid is ready to be connected at the grid, an interconnection study or model is required to be developed as per the interconnecting ISO’s requirement. The time-domain transient model is highly complex and developed in PSCAD or PSS-E as per the ISO’s requirements.
