In port areas, with the progressive increase in maritime traffic, the problem of pollution is crucial especially when the port is near to an urban area. The cold ironing allows a reduction of pollutants satisfying the power demand of ships while they are at berth, replacing on board diesel engines. In this paper, the methodology of analysis of the electrical loads required by ships concerns the typical week of each month over a one year period. The power is provided by a cogeneration plant powered by natural gas. It is flanked by a Compressed Air Energy Storage system since the energy demand is linked to the presence of ships in port and so very variable over time. The heat waste is recovered in a heating district network for overall optimization. At last, the economical aspect has been evaluated to prove the feasibility of the whole system. The results, for the case of the port of Ancona, show that a 1.5 MW and 2 MW cogenerator covers the 83.05% and 92.5% of the electrical need of ships respectively, and the 61% and 74% of the thermal need of buildings over the period analysed. The coverage of the CAES system is not influenced by the rated power.

在港口地区，随着海上交通的不断增加，污染问题至关重要，尤其是当港口靠近市区时。冷熨可以减少污染物，满足船舶停泊时的功率需求，替代船上的柴油发动机。在本文中，分析船舶所需电力负荷的方法论涉及一年中每个月的典型星期。该电力由天然气供热的热电厂提供。它的两侧是压缩空气储能系统，因为能源需求与港口中船舶的存在有关，因此随时间变化很大。余热通过供热区网络进行回收，以进行整体优化。最后，从经济方面进行了评估，以证明整个系统的可行性。结果表明，以安科纳港为例，一台1.5 MW和2 MW的热电联产发电机分别满足了船舶电力需求的83.05％和92.5％，以及建筑物上方热能需求的61％和74％分析的时期。CAES系统的覆盖范围不受额定功率的影响。
