The smart micro-grid (settings to match UK electricity grid) can be found here. The output results from the scopes should then be compared to the output of the validation script. To run the theoretical validation case, the validation grid should then be opened in MATLAB Simulink and run over a 24h period. The simulations also require the download of the Simscape package. Getting Startedīefore running the validation case or the experimental simulation, it is necessary to load the default MATLAB solar panel data in the MATLAB workspace. For organisations that have invested in CHP, battery energy storage allows the CHP to remain operational without power supply from the grid, providing enough power to keep the site running independently and uninterrupted.Repository with Smart Grid simulation code from MATLAB and Simulink along with a report on the Simulation of a Smart Grid at a microgrid level. Energy generated on site can be fully used or sold back to the grid if not needed at a peak price. These allow energy to be stored for use when most beneficial. A smart microgrid will have a control system capable of automatically monitoring, predicting, and controlling the power flows, deciding when best to generate, store, and use the energy available.īattery energy storage is an integral part of smart microgrids. Whatever makes up the network of generation and loads, a control system is required to manage the microgrid. With the ability to run independently from the National Grid, a microgrid can protect a site from power disruptions and reduce costs and carbon emissions from electricity use. Typically, there will be on-site power generation, from solar, wind, or Combined Heat and Power (CHP), and multiple buildings or equipment requiring specific power loads at certain times. The specific aims of a smart microgrid will determine what elements they feature and how they are managed. Integrating various green energy technologies also makes smart grids cleaner, while reduced outages and lower costs through smart monitoring also offers lower energy costs. This includes more accurate preventative maintenance and greater energy efficiency by using data to identify areas of improvement. Smart grids help to reduce energy consumption and costs through intelligent application of data. This provides utility providers and end users alike far greater insight and access to data, as well as being able to dynamically monitor and control equipment across a grid from a central location. Smart grids are part of the wider ‘Internet of Things’ technology concept, where increasing amounts of equipment and infrastructure has communication capabilities and is interlinked. Lastly, smart grids require sufficient digital communication infrastructure to allow the different elements of the grid to be connected, monitored and controlled in real-time. For larger, utility-scale smart grids, storage continues to occupy a key role, storing generated energy as well as allowing end users to better engage with the smart grid, pushing and pulling electricity as required rather than being passive bill payers. In the case of smart microgrids, batteries increasingly form the centre of the grid and are typically accompanied by sophisticated energy management software that monitors other aspects of the smart grid and intelligently manages their operation. The ability to store electricity reliably opens up much greater efficiency across a smart grid, allowing excess generation to be stored and more easily balancing demand across multiple end-users. Typically, generation technology will be supplemented by storage, usually battery energy storage systems (BESS). Intelligent monitoring and controls allow this mix of generation to be used effectively across a number of different sites and end users, dynamically balancing available supply with demand. A range of technologies can be incorporated into a smart grid to provide multiple energy vectors, such as solar and wind providing electricity or heat pumps and biomass providing heat. These are often accompanied by controls and demand response capabilities that are behind the meter in the case of utility smart grids.Īdditionally, smart grids will incorporate distributed generation, typically spread across a large number of small-scale power producers. The first of these is advanced metering infrastructure, which gives them their commonly used name: smart meters. A smart grid will typically incorporate a number of different common elements.
