Energy Storage for a Sustainable WorldRead More
Fundamentally, countries worldwide are actively making steps towards creating more energy efficient and yet cleaner cities. As the energy industry moves away from carbon-heavy production, renewable energy and storage is being critical for delivering on the
demand while securing the future of world energy and playing a prominent role in a grid that is migrating to a higher penetration of renewable energy, smarter grids, and flexible grids.
However, high penetration creates power transmission instability challenges, thus Grid Operators require stringent dynamic and static grid support features for Power Conversion Systems.
For the challenge of energy stability, Makelsan has solutions from kW to MW
Challenges that Makelsan DRM can address:
• Output variability,
• The temporal (time-related) mismatch between generation and demand,
• Uncertainty regarding weather forecasts, and
• Undesirable electrical effects on the electrical grid caused by some RE generation
Makelsan DRM solution offers proven hardware to meet storage and grid support challenges.
DRM is a fully integrated turnkey energy storage solution that are ready for connection to medium-or high-voltage grids and cover a power range of hundreds of megawatts. With over 40 years experience in power eletronic, Makelsan has developed DRM Energy Storage System for on grid and off grid application with typical loads between 400 kW and 1 MW.
The DRM system is fully compliant with grid systems to import and export power inline with the voltage and frequency regulations, FFR and DFFR schemes required by utilities to support the grid. The DRM can be used to support the stabilisation of the grid to manage the consumption and the production of renewable energy.

Complete Solution From Single Source
The containerised DRM system is available with 400kW, 500kW, 600kW, 1000kW capacities by using 20GP or 40HQ containers. Fully bunded ISO Container is designed with personnel and maintenance access doors and has air conditioned seperate converter and battery compartments.
With peak shaving, the energy is stored during periods of low demand (overnight, troughs in the day) and discharged during periods of high demand when the monthly peak consumption could be set. Given the anticipated cycling, duration and power needs of peak shaving, energy storage is very effective. The higher the peak related to the duration of the peak, the better the energy storage economics.

The UK electricity grid operates at a frequency of 50 Hz, meaning current flows first one way, and then the other, 50 times per second. National Grid is responsible for managing the frequency, and is required by law to keep it between 49.5 Hz and 50.5 Hz under normal conditions.
If the frequency moves much beyond these limits, or changes rapidly, some generators will automatically disconnect from the grid for safety reasons. The end result can be unexpected power cuts and cause significant inconvenience and economic impacts.
DRM Demand Response Module installed at ENWL, Whitbirk plant provided ability to regulate grid frequency in both directions. When there is a grid overfrequency (generation > demand) inverter power output is curtailed and this energy is stored. When there is a grid under-frequency (generation < demand) inverter power output is increased by discharging the batteries and injecting more power to the grid.
The hybrid system Demand Response Module comprises a generator set and containerised power module (static power converter + batteries for 30 mins back up + BMS + EMS). The system can deliver up to 440kw and is specifically designed to operate with biodiesel B100 making it the most versatile system of its type on the market.
The customer ENWL used the existing connection to the grid to balance the frequency of the grid via importing or exporting electricity. Due to where the grid response module is placed it can also provide benefits to the commercial site through imbedded benefits such as grid resilience, TRIAD and DUoS (Distribution Use of System) avoidance thus making huge energy savings for the site owner.
Frequency Regulation / DFFR service that helps National Grid control system frequency around UK in real time by balancing electricity demand with generation.
Following installation, the site used the Makelsan DRM’s charging and discharging profile to balance grid import and export.
During tests with National grid Aggregator Makelsan DRM has been approved for the control of energy usage during peak demand and high pricing periods (DUoS), reducing peak demand charges and offering potential revenue to be gained through grid contracts (Demand Side Response).
Some of national grid tests done during installation can be seen in the following charts:
Based on demand (import/export) batteries are discharged or charged. Since the trend is more export, battery charge % is slightly decreasing. As shown in the chart R (response) to D (demand) is very fast.
In case battery voltage come to low level, genset helped to charge them, then stopped.
The EIF 2018 - 11th International Energy Congress and Exhibition-the biggest energy event of Turkey held in Ankara at November 8-9.
At the exhibition which brings together leading domestic and foreign professionals, foreign ministers and investors in the energy sector , Makelsan as the energy storage sponsor of the congress-introduced its groundbreaking new DRM product- Turkey's first and only energy storage system which is manufactured 100% locally.
The new DRM - Energy Storage System which currently being used in international and proved its competence with outstanding performance far above the criteria determined by European electricity producers, is now launched in Turkey to lead the national energy revolution.
With the aim of increasing the share of renewable energy resources up to 30% in 2023, Makelsan is developing new technologies to minimize grid problems and reduce the additional grid investments and with its new DRM Energy Storage System aims to increase the efficiency of energy industry and offers an excellent local oppurtunity for energy sector proffessionals who wants to discover value added salutions minimizing costs.
