The sparsity of signals and images in a certain trans-form domain or dictionary has been exploited in many applications in signal and image processing. Analytical sparsifying transforms such as Wavelets and DCT have been widely used in compression standards. Recently, synthesis sparsifying dictionaries that are di-rectly adapted to the data have become popular especially in appli-cations such as image denoising, inpainting, and medical image re-construction.

说明：  假设微电网中有风、光、微型燃气轮机、蓄电池，且已知各时段负荷需求；微电网可并网运行，当微网内部发电量较大时，可向电网卖电，而当内部发电不足时，可从大电网购电，价格参考实时电价。考虑各机组运行成本、燃料成本、污染物处理成本、以及买卖电支出或收益。该程序可解决在并网运行模式下，各机组出力如何分配才能达到经济最优的问题。(Suppose there are wind, light, micro gas turbines and batteries in the microgrid, and the load demand is known at each time period; the microgrid can be connected to the grid for operation; when the microgrid has a large amount of internal power generation, it can sell electricity to the grid, and when the internal power generation is insufficient At that time, electricity can be purchased from the big grid, and the price can be referenced to real-time electricity prices. Consider each unit's operating costs, fuel costs, pollutant disposal costs, and trading power expenses or benefits. This procedure can solve the problem of how each unit's output can be distributed to achieve economical optimization in the grid-connected operation mode.)
