The technical concept include Permanently Islanded micro grid network which is standalone network .
The proposed network must produce all of the generation locally that will be consumed by the loads in the network.
Our main focus in our design is to Maximizes Use of PV as much as available in the specific sites in Cameroon. When renewable generation (hydro, wind, solar) and the available method of storing power (specific battery) is available, the designed system is able to maximize the use of renewable generation by enabling energy storage when it determines there is excess renewable power available or it is economically viable to do so. At a later time when there is not enough renewable generation to support the load, the system can dispatch this low cost stored energy to meet the load requirements in the most efficient manner possible.
Our comprehensive microgrid approach includes advantages such as:
During periods of time where there is more renewable generation available than is required to support the, or when there is additional generation margin due to lightly loaded generators, our system can initiate the storage (battery) of “fuel”.
Using cost information that was entered at the time of configuration of the system, the optimization algorithms of our MG system analyze the excess generation available and determine if it is economically beneficial to store energy at that time. The system will take into consideration the amount of time it takes the storage medium, to operate efficiently and how long it must run for prior to seeing benefits, before it initiates the storage process.
The distributed generators that are connected to the microgrid are currently monitored by the MG system and their output is constantly tracked. A forecast for the expected output of generation from renewable sources over the next prediction horizon (e.g. 24 hours) is then created to predict the contribution to the overall generation that will be supplied by these renewable sources.
Similar to the load forecast predictions, if the actual measured generation from available sources differs from what the MG system forecasts for reasons such as a drop in wind or an increase in clouds as compared to previous days, the MG system will continually adjust its forecast to make the best predictions for the contribution of renewable generation that will be available to support the required loads in the microgrid.
Islanded Mining and Remote Communities One of the biggest challenges that permanently islanded remote and mining communities face is to reduce total cost of energy, primarily driven by fossil fuel cost and quite exorbitant fuel transportation costs. Although, many of these remote communities may have some form of a renewable resource, such as run of a river hydro, small bio-gas plant, wind, or solar, unfortunately because of lack of smart control system infrastructure, they are primarily dependent upon fossil fuel based generation for their energy needs. The Grid IQ MCS system can help many of these remote islanded communities by optimizing the operation of existing assets and also by helping integrating renewable energy resources into the existing network. Such capability not only helps these communities to reduce the total cost of energy, but can also help reduce the GHG emissions and resulting adverse environmental impacts.
