Abstract

ABSTRACT The management of energy systems with a high share of renewables is a challenge for grid planners and operators, as weather and energy demand do not always coincide. Investigating the energy autonomy of cities and their local energy resources can help to overcome this challenge. To this end, real energy demand data from the city of Loja, Ecuador, and wind energy generation from a nearby wind farm were compared. This showed that wind energy provides 53% of the city’s demand. It is exposed that despite the excess energy, the wind farm’s ability to supply the city with electricity is limited to about 74% when the wind farm is expanded to twice its rated capacity. The results show that in order to improve the autonomy, other energy sources, such as photovoltaic, as well as useful size energy storage are needed.

城市能源自治评价:促进能源转型的工具

由于天气和能源需求并不总是一致，可再生能源占比高的能源系统的管理对电网规划者和运营商来说是一个挑战。调查城市的能源自主权和当地的能源资源可以帮助克服这一挑战。为此，对厄瓜多尔洛哈市的实际能源需求数据和附近风电场的风力发电进行了比较。这表明风能提供了53%的城市需求。暴露出，尽管有多余的能源，当风电场扩大到额定容量的两倍时，风电场为城市供电的能力限制在74%左右。结果表明，为了提高自主性，需要其他能源，如光伏，以及有用的尺寸储能。
