The enhanced integration of the renewable energy within the current power systems have necessitated the need to possess smart and flexible and economically feasible dispatch strategies. Though solar and wind farms do not pollute the environment, they are extremely unreliable as a result of weather variations and therefore conditions need real-time decision-making, especially where there is a grid connection and therefore the market prices are prone to change. This research paper outlines an optimisation strategy of a Market-Aware instead of Learner on Reinforcement Learning (RL) to optimize the functionality, grid stability and economic operations of united solar-wind farms.
It is a framework integrating all of the dynamic electricity market physicals, time-of-use tariffs, demand-response trends, and renewable generation foresees in a single RL environment. The deep actor-critic RL model is optimized to optimize solution according to energy dispatch, e.g. the extent of power supplied to the grid, the extent of power charged and discharged battery storage and when and how to curtail the system strategically. The reward system is established in order to push the overall cost of operation, power wastage and maximize profits of the market involvement.
The RL agent can learn adaptive strategies much better than the conventional rule-based and deterministic optimization methods through the application of real-world solar and wind generation data in the shape of a simulation model. Results show that curtailment had significantly reduced, there was increased utilization of storage and the interactions on the grid and improved economic returns. The model of the real-time market fluctuations is dynamically adjusted and decisions made to afford the flexibility of the profitable operations in the farms.
The paper provides sufficient content evidence, that the market-conscious RL may be implemented as a strategic control instrument in the following generation of smart renewable energy farms that may be used to increase the energy resilience, sustainability and economic maximization in the next generation power networks
