  "title": "How to Smartly Manage Power in Small Grids with Renewable Energy",
  "original_title": "Method for real-time scheduling of multi-energy complementary micro-grids based on rollout algorithm",
  "summary": "This patent describes a method for quickly and efficiently planning how different energy sources (like solar, wind, and batteries) work together in a small, local power grid, especially when renewable energy output changes unexpectedly.",
  "what_it_does": "The patent outlines a four-step method (Claim 1) for real-time scheduling of \"multi-energy complementary micro-grids.\" First, it sets up a \"moving-horizon Markov decision process model\" to represent the micro-grid's scheduling problem, considering unpredictable \"new-energy outputs\" and defining various \"constraint conditions\" like battery limits and power exchange with the main grid. Second, it establishes a \"target function\" to minimize the micro-grid's operating cost. Third, it divides the scheduling into smaller intervals and finds an initial, basic plan using a \"greedy algorithm.\" Finally, it refines this basic plan using a \"Rollout algorithm\" to achieve a high-speed, efficient real-time schedule. For example, in a small community micro-grid with solar panels, wind turbines, and a battery, this method could instantly decide whether to use solar power, charge the battery with wind, or buy/sell electricity from the main grid, all while keeping costs low and adapting to sudden changes in weather.",
  "what_it_does_not_cover": [
    "Does not cover scheduling methods that do not use a \"moving-horizon Markov decision process model\" for the micro-grid.",
    "Does not cover scheduling methods that do not establish a \"target function\" specifically aiming for minimum operating cost.",
    "Does not cover scheduling methods that do not use a \"greedy algorithm\" to find an initial basic feasible solution.",
    "Does not cover scheduling methods that do not use a \"Rollout algorithm\" to find the final solution based on the basic feasible solution.",
    "Does not cover micro-grid scheduling that ignores specific constraints like battery operating limits or power exchange limits with the main grid."

  "abstract": "The invention relates to a method for real-time scheduling of multi-energy complementary micro-grids based on a Rollout algorithm, which is technically characterized by comprising the following steps of: Step 1, setting up a moving-horizon Markov decision process model for the real-time scheduling of the multi-energy complementary micro-grids with random new-energy outputs, and establishing constraint conditions for the real-time scheduling; Step 2, establishing a target function of the real-time scheduling; Step 3, dividing a single complete scheduling cycle into a plurality of scheduling intervals, and finding one basic feasible solution meeting the constraint conditions for the real-time scheduling based on a greedy algorithm; and Step 4, finding a solution to the moving-horizon Markov decision process model for the real-time scheduling of the multi-energy complementary micro-grids by using the Rollout algorithm based on the basic feasible solution from Step 3. With the consideration of the fluctuations in the new-energy outputs, the present invention solves the problems of low speed and low efficiency of a traditional algorithm at the same time, enabling high-speed efficient multi-energy complementary micro-grid real-time scheduling.",
