Demand response contribution to effective inertia for system security in the GB 2020 gone green scenario

Power systems are facing complex challenges in order to achieve environmental targets, such as a strong abatement of CO₂ emissions. Hence, an increasing share of renewable energy sources (RES) will change the generation portfolio. This is likely to push network operation into a risky territory, due to a lack of system inertia. This paper quantifies the impact of providing `effective inertia´ by controlling domestic thermostatic loads. This inertial support mechanism would permit full absorption of available wind power even for those scenarios characterized by low demand and high wind penetration.
