Hybrid power station
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryHybrid power plants, also known as solar plus storage or wind plus storage projects, have gained significant traction in recent years. These projects combine solar energy or wind energy with battery energy storage. The result is a somewhat dispatchable renewable energy power plant, which can provide smoother (less-volatile) energy, and can shift time of delivery to avoid the dreaded duck curve (or seek out more favorable pricing windows).
These hybrid power plants are thought to be better able to compete with dispatchable fossil fuel resources by addressing intermittency and delivery timing, which are consistently raised concerns about wind and solar energy. Hybrid power plants therefore appear on the surface to be an excellent approach. But there are significant downsides as well.
Let us compare two hypothetical facilities. One is a hybrid power plant—a standard solar plus storage project. The other is what I call a “solar and storage” project. Solar and storage projects don’t actually exist, but make a convenient theoretical comparison.
Both facilities comprise a solar system and a lithium-ion battery energy storage system. The difference is that the hybrid project operates the solar plus storage systems together, through a single interconnection, as a single combined project. The solar and storage project, on the other hand, is operated as two co-located but separate facilities. Solar and storage are separately interconnected and separately operated.
The solar energy portion of both projects have to meet the requirements of the applicable renewable energy certificate (REC) or renewable portfolio standard (RPS) program in their jurisdiction. They also have to make sure to maintain investment tax credit (ITC) eligibility. The difference between them is that the storage portion of the solar plus storage project is also included for REC/RPS and ITC purposes. Because it is part of the solar project, the battery has to act like a solar project, while the storage is not included for the solar and storage project.
Project ObjectivesThe objective of our project is to meet the load of different applications using our designed hybrid system, while minimizing costs. Our model has to test the for the presence of a potential complementary relationship between wind and solar energy systems under similar weather conditions.
Many different applications are considered, and the optimal design parameters for each application are found, meaning the optimum number of solar arrays and wind turbines, as well as the optimum rotor diameter and height.
Project Implementation MethodWe will implement our project through waterfall model. Phases of implemented method
as follows:
1. Requirement gathering and Analysis: All possible requirements of the system to be
developed are captured in this phase and documented in a requirement specification
document.
2. System Design: The requirement specifications from first phase are studied in this
phase and the system design is prepared. This system design helps in specifying
hardware and system requirements and helps in defining the overall system
architecture.
3. Coding / Implementation: With inputs from the system design, the system is first
developed in small programs called units, which are integrated in the next phase. Each
unit is developed and tested for its functionality, which is referred to as Unit Testing.
4. Integration and Testing: All the units developed in the implementation phase are
integrated into a system after testing of each unit. Post integration the entire system is
tested for any faults and failures.
5. Deployment of system: Once the functional and non-functional testing is done; the
product is deployed in the live environment.
The main goals our project are:
1. Continuous power supply :The hybrid solar systems provide power continuously, without any interruption, as the batteries connected to them store the energy.
2. Low maintenance cost :The maintenance cost of the hybrid solar energy systems is low as compared to the traditional generators which use diesel as fuel.
3. Load management :Unlike traditional generators, which provide high power as soon as they turned on, most of hybrid solar power systems manage load accordingly.
