Whitby: Swing Bridge could be 'flexibly pedestrianised'
Whitby Swing Bridge could be "flexibly pedestrianised" if plans to improve the area are approved this Yorkshire Council will discuss proposals to install new traffic lights at the A171 New Bridge and Spital Bridge bridge itself, which was built in 1909 and links the east and west sides of the town, would be made more would start from April if the council gives the plan the go-ahead. The crossing over the River Esk often becomes crowded during peak visitor times and there have been previous trial closures to business owner Alex Boyd told the Local Democracy Reporting Service that he welcomed the proposals - but had concerns about the impact four months of work would have on him and other traders in the area."From what I've seen I think it's quite a nice idea, obviously we might lose a little bit of trade in the sense of people driving past through the day, but most of our 'pull-ins' are at night-time anyway", he Boyd added that projects like the Market Place improvements had been "rumbling on for years" so he would "see how it goes". Minimise impact The businessman also had concerns about the disruption the works would cause heading into the busy summer season."I think they're going to have to be sensible and maybe look at everything with us, and work together to minimise the impact on, not only my business, but the businesses surrounding us", Mr Boyd added. According to a report prepared for the meeting on Friday, there is a "practical need to signalise the junction of New Bridge, Spital Bridge, Helredale Road and Larpool Lane".It said without doing so, it would be "very difficult" to proceed with the remainder of the Harbourside scheme. The £2.3m project was proposed and funded through the Whitby Town Deal and is made up of five further proposals across the town, all of which were part of a consultation in than 64% of those consulted said they were in favour of introducing traffic signals at Spital Bridge Junction, the report acknowledged that signalising the junction would improve conditions for drivers exiting on the side roads and for pedestrians but would introduce queuing on New Bridge and Helredale added that "the average queuing on the signalised junction as a whole would be increased, however, queuing on the Spital Bridge arm would decrease".Whitby Town Council said it supported the proposal in principle and welcomed the introduction of the additional signal-controlled crossing to highlights from North Yorkshire on BBC Sounds, catch up with the latest episode of Look North or tell us a story you think we should be covering here.

A New Paradigm for Power Grid Operation
Power grids operate like an intricate ballet of energy generation and consumption that must remain perfectly balanced at all times. The grid maintains a steady frequency (60 Hz in North America and 50 Hz in many other regions) by matching power generation to demand in real-time. Traditional power plants with large rotating turbines and generators play a crucial role in this balance through their mechanical inertia—the natural tendency of these massive spinning machines to resist changes in their rotational speed. This inertia acts as a natural stabilizer for the grid. When there's a sudden change in power demand or generation, such as a large factory turning on or a generator failing, the rotational energy stored in these spinning masses automatically helps cushion the impact. The machines momentarily speed up or slow down slightly, giving grid operators precious seconds to respond and adjust other power sources. However, as we transition to renewable energy sources like solar and wind that don't have this natural mechanical inertia, maintaining grid stability becomes more challenging. This is why grid operators are increasingly focusing on technologies like synthetic inertia from wind turbines, battery storage systems, and advanced control systems to replicate the stabilizing effects traditionally provided by conventional power plants. Alex Boyd, CEO of PSC, a global specialist consulting firm working in the areas of power systems and control systems engineering, believes the importance of inertia will lessen, and probably sooner than most people think. In fact, he suggested stability based on physical inertia will soon be the least-preferred approach. Boyd recognizes that his view, which was expressed while he was a guest on The POWER Podcast, is potentially controversial, but there is a sound basis behind his prediction. 'The premise behind stability based on inertia is: the inertia makes it hard to move the way the grid operates quickly, and so as a result, you gain stability out of it,' Boyd explained. 'With the evolution to power electronic-based stability services, we're going to have a lot more options to have precise control and change things much more quickly than we can today.' Power electronics-based systems utilize inverter-based resources, such as wind, solar, and batteries. These systems can detect and respond to frequency deviations almost instantaneously using fast frequency response mechanisms. This actually allows for much faster stabilization compared to mechanical inertia. Power electronics reduce the need for traditional inertia by enabling precise control of grid parameters like frequency and voltage. While they decrease the available physical inertia, they also decrease the amount of inertia required for stability through advanced control strategies. Virtual synchronous generators and advanced inverters can emulate inertia dynamically, offering tunable responses that adapt to grid conditions. For example, adaptive inertia schemes provide high initial inertia to absorb faults but reduce it over time to prevent oscillations. Power electronic systems address stability issues across a wide range of frequencies and timescales, including harmonic stability and voltage regulation. This is achieved through multi-timescale modeling and control techniques that are not possible with purely mechanical systems. Inverter-based resources allow for distributed coordination of grid services, such as frequency regulation and voltage support, enabling more decentralized grid operation compared to centralized inertia-centric systems. Power electronic systems are essential for grids with a high penetration of renewable energy sources, which lack inherent mechanical inertia. These systems ensure stability while facilitating the transition to low-carbon energy by emulating or replacing traditional generator functions. 'I do foresee a time in the not-too-distant future where we'll be thinking about how do we actually design a system so that we don't need to be impacted so much by the physical inertia, because it's preventing us from doing what we want to do,' said Boyd. 'I think that time is coming. There will be a lot of challenges to overcome, and there'll be a lot of learning that needs to be done, but I do think the time is coming.'
