  "original_title": "Combined heating power and cooling apparatus with energy storage type adapted to an active distribution network and its method",
  "summary": "This patent describes a complex energy system that combines electricity generation, heating, and cooling with energy storage to help power grids manage their load more flexibly.",
  "what_it_does": "The patent details a combined heating, power, and cooling (CHPC) apparatus designed for an \"active distribution network\" (a smart power grid). This system includes a \"generation apparatus\" (like a power plant engine) connected to a \"generator\" to make electricity. It uses various \"flue gas-water heat exchangers\" to capture heat from the generation process. Crucially, it incorporates both a \"waste heat recovering and absorbing heat pump\" and an \"energy storing electric heat pump,\" along with \"high temperature energy storing canister\" and \"low temperature energy storing canister\" for storing heat and cold. This setup allows the system to adjust how much electricity it puts onto the grid, helping the grid handle changes in demand, rather than being stuck in older modes where electricity output was solely determined by heating or cooling needs. For example, during times of low electricity demand but high heating needs, the system can store excess heat instead of generating more electricity than the grid requires.",

    "Combined heating, power, and cooling systems that do not include specific energy storage components like \"high temperature energy storing canister\" and \"low temperature energy storing canister.\"",
    "Energy systems that do not incorporate both a \"waste heat recovering and absorbing heat pump\" and an \"energy storing electric heat pump.\"",
    "Systems that do not use \"flue gas-water heat exchangers\" to recover heat from the generation apparatus.",
    "Power generation systems that cannot actively regulate their generated electricity to participate in grid load management.",
    "Simple combined heat and power (CHP) systems that operate solely by \"determining electricity based on heat\" or \"determining electricity based on cooling.\""

  "abstract": "The Application relates to a combined heating power and cooling apparatus with energy storage for an active distribution network and its operating method. The apparatus is comprised of a generation apparatus, a generator, a waste heat recovering and absorbing heat pump, a high temperature flue gas-water heat exchanger, a medium temperature flue gas-water heat exchanger, a low temperature flue gas-water heat exchanger, an energy storing electric heat pump, a high temperature energy storing canister, a low temperature energy storing canister, a cooling tower, a number of circulating water pumps and a number of valves. The operating method changes the traditional operation modes of the system “determining electricity based on heat” and “determining electricity based on cooling”, causes the system to regulate power of the generated electricity on grid, participate in the regulation of grid load, solve the problem of a limited ability of generation peak regulation due to the inter-coupling of power generation, heat supply and cooling supply.",
