Overcoming grid congestion

Dutch grid operators are investing billions of euros to expand the electricity network. However, the Dutch electricity grid was not originally designed for this scale of decentralised energy generation and flexible demand. In many parts of the Netherlands, grid operators are experiencing or expecting a structural shortage of transport capacity on their electricity grids.

In the long-term, large-scale and high-voltage transmission lines are needed, but they can take years to develop and build, according to the report. In the near-term, GETs can increase transmission capacity on existing wires, relieving at least 40% of congestion in many cases, Grid Strategies said.

“Smart energy management solutions let us turn grid constraints into win–wins for all sides,” says Carsten Schäfer, Senior Product Manager Innovation, at gridX. To conclude, industry experts stress that effective congestion management transforms a challenge into an opportunity for the energy transition. Strategic deployment of storage under EMS and HEMS control increases the effective capacity of existing infrastructure while supporting decarbonization by firming renewable supply. In distribution networks, community batteries and aggregated home BESS can absorb evening peaks – when many appliances and EVs run simultaneously – relieving stress on neighborhood circuits. At e-mobility sites, virtual grid expansion allows charge point operators to go above physical grid limitations by intelligently integrating and leveraging BESS and local PV.

Battery storage and hybrid assets absorb local surpluses and discharge during peaks, acting as a buffer between generation and demand. Demand response shifts consumption away from constrained hours or locations, smoothing peaks and lowering flows across bottlenecks. Export-limited regions with high levels of wind and solar often experience curtailment when transmission lines become overloaded. During periods of limitation, day-ahead prices can differ greatly from real-time outcomes, creating basis risk for traders, suppliers, and corporate buyers. Overall, congestion acts like a traffic jam for the system, stopping it from working at its best and increasing costs for everyone involved, including consumers and market participants.

These innovative solutions collectively contribute to a more resilient, efficient, and sustainable energy grid‍ Before we dive into solutions, let’s first explore what exactly grid congestion is. While it’s difficult to manage electricity flow, system operators can influence how much electricity generators produce.

Heimdall’s machine learning uses the data to help grid operators plan how they’ll route electricity for the next day. Heimdall combines the information with local weather-forecast data—particularly wind speed, which has a cooling effect on power lines and can thus increase their capacity. So for all but the hottest days, transmission lines could carry significantly more electricity, if grid operators only knew the actual temperature of the wires. Historically, grid operators have estimated the capacity of lines based on average seasonal temperatures—a fixed value called static line rating.

What is congestion management?

The system uses weather forecasts to predict the temperature and capacity of the lines for the next day, which is especially useful for day-ahead planning. This allows grid operators to take advantage of the unused headroom by maximizing the current in that line. Together, the devices form a system that calculates how much current these high-voltage lines can safely carry based on real-time weather conditions.

• The package also includes 2 guidance documents on efficient and timely grid connections and the design of 2-way contracts for difference.
• This targeted curtailment – usually applied to photovoltaic (PV) and wind – prevents overloads and stabilizes voltage without shutting down the entire plant.
• Today’s grid relies heavily on long-distance transmission lines to move electricity from generation sources to population centers.
• This often comes from a disconnect between supply and demand, especially with the increase of renewable energy sources that can be a bit unpredictable.
• The implementation of bidding zone splits that prove to enhance market outcomes, is recommended to establish better incentives for efficient operation.
• Let’s look at Pennsylvania just outside of Scranton on an overcast Wednesday with seasonable weather, and let’s zero in at around 5 a.m.

• “This makes DLR a strategically important part of the integration of renewable energy.” Gridraven’s system can increase capacity of power lines by 30 percent on average, according to the company.
• Understanding where congestion is happening today and how it’s changing can be the difference between a project going ahead and being cancelled.
• This causes bottlenecks in many regions, known as grid congestion.
• Laurens emphasises that continuous innovation is essential to effectively address grid congestion, as operators can only achieve efficiency by integrating the latest techniques into daily operations.

Heimdall has deals with six additional U.S. utilities bringing its technology to 13 states. Its first major U.S. project, in Minnesota, is helping the utility Great River Energy increase its capacity by 25 percent nearly 70 percent of the time, according to the utility. In Heimdall’s approach, one of the key metrics its sensors track is line sag; as metal wires get hotter, they expand and make the line droop. The strategy, called dynamic line https://compitionpoint.com/choosing-industrial-sewer-specialists-key-considerations-and-competitive-advantages/ rating, or DLR, is being rapidly adopted in North America and Europe as an antidote—at least in the short term—to grid congestion woes.

What is redispatch?

Whether at industrial scale through EMS or at household scale through HEMS, these measures keep the grid more efficient by using available capacity more evenly across the day. This market-based congestion management lets the DNO relieve specific bottlenecks at critical times, deferring the need for immediate physical upgrades. First, §9 of the Renewable Energy Sources Act (§9 EEG) allows grid operators to https://texas-news.com/how-to-succeed-as-the-owner-of-your-own-transport-business-in-2023.html temporarily reduce grid feed-in from renewable generators when local or regional grid capacity is exceeded. At this summit, ABN AMRO shares its views on the challenges that society, the economy and its own clients face, and addresses possible solutions. This means more power supply over the course of the day, simply because grid capacity is used more efficiently.” “An important advantage of the new, joint contract forms is that companies who have joined an energy hub decide among themselves how they use the available capacity, by agreeing among themselves how much power they can each use at any given time.

Power grid congestion happens when transmission bottlenecks block the cheapest available generation from meeting demand. By understanding how this process works and its contribution to market volatility, curtailment, and constraint costs, we can better appreciate the complexities of today’s power markets. As we continue to innovate and invest in energy infrastructure, we can overcome the challenges of grid congestion and pave the way for a resilient and sustainable energy system. Advanced grid management techniques, including dynamic line ratings and behind-the-meter solutions, are crucial in alleviating congestion.

British distribution network operators (DNOs) are transforming into DSOs by running local flexibility markets. In the near term, however, a key strategy is unlocking flexibility at the distribution level to manage constraints more dynamically. These congestion costs ultimately fall on consumers and have topped £1 billion in recent years, highlighting the need for new solutions beyond simply turning off renewables. While interconnectors to Europe, such as the North Sea Link to Norway or the IFA to France, provide flexibility by enabling imports and exports, internal transmission bottlenecks mean this trading potential is not always fully used. Together, §9 EEG and §14a EnWG form a regulation-backed congestion management framework that uses both supply-side and demand-side flexibility to integrate more renewables and electrification without waiting for lengthy grid upgrades.

We’re now facing exactly the same challenges we’ve seen unfold in the Netherlands — just a few years later. And for years, this helped Belgium avoid the severe bottlenecks seen in neighboring countries like the Netherlands. As the transition to renewables accelerates, the electrical grid faces growing pressure from constraints like grid congestion.
