Energy Storage Systems in Micro Grid Application
With the upcoming trends for renewable energy, it is a requisite to catalyse reliability for the Energy Distribution. Based on the same, it has also been imperative to check the Power Quality parameters coforming to IEC 61000-3-6 standards. Though, we do have the current grid technology in mitigating these events coforming to the standards, the response level is often compromised to a few ms to seconds. This is reflected on the customers at the down line loads connected. This in turn affects the system components & loads compromising reliability & efficiency.
Micro Grids are essential to reduce the fauly MVA within a smaller network that excalate it within the macro grid network. Therefore, with ESS at common nodes, we can address the frequency dip at heavy load nodes with quick responders.
To mitigate the challenge of power dip, solutions such as power dense Dry Cells are integrated to the Microgrids. This will provide instantaneous compensation to the sudden power fluctuation in the grid. Given the vulnerability in power sinks, RoCoF and Transients that the grid faces; the current mitigatory instruments must be arbitraged by technologies that augments the action in subcycle to a few cycles time frame. The new solutions must be able to provide synthetic inertia to the node by rapidly injecting & absorbing the power.
Another solution is employing Hydrogen generation & storage from excess power generated from the wind turbines. With excess wind power that is available during night time & no load curves; we can store the excess power in hydrogen that functions much efficient than battery storage. Given the ample rain fall in the country & excess wind power, ECOGEN can support the ESO with true sustainable & socially responsible solutions.
Electrolysers & Fuelcells have become a trend setters eliminating the need for large scale BESS providing CHP solutions and ready power. However, integrating it to the MV network & the production capacity is still explored while it’s widely applied in the LV network.
By combining Dry Cell & BESS with Fuel Cells, we create a rugged microgrid that is self sustainable. It formulates a rapid response system with quick charge/discharge functionality along with an ESS that is designed for optimal load. This not only eliminates the need for an oversized equipment design, but, also escalates the response in a smart & unique operative concordance.
Given the adoption of Graphene technology in many power system solutions, the power & energy density has been condensed to smaller surface areas providing a multi-fold applicability based on the device employment. An added advantage of new technological advancement is having long operating hours & extended warranty period of 10-25 years.
Given the trends for intermittent concatenation of new energy sources in to the grid, power firming is imperative. With a hybrid-ESS integrated Microgrids, we are looking at multiple value streaming that can be bridge the Power Systems together. This will further augment DVR (Dynamic Voltge Restorers) & EFRs (Enhanced Frequency Response). Multifaceted response based on the timing can be defined based on the nature of solution that is integrated; thereby providing firmer bridging, ramping & compliance to the Utility regulatory advice. UK based DNOs & IDNOs finds it particularly interesting given the current demographic trends that the energy market is facing.
Therefore, sustainable Microgrids trends the energy market being able to not only tie in the new energy sources, but also provide better Power Quality sustainably. Should you require more information on how this can be achieved, feel free to contact us.
