本文评估了网络经济建模方法在设计具有可再生能源和常规发电机的能源系统中的准确性。网络方法将系统建模为需求、生成器、市场和资源等过程的网络。该模型通过在系统的节点之间交换价格和数量信息来实现解决方案。这种公式非常灵活，只需很少的时间来构建和修改模型。本文报道了一种用光伏发电和基峰化石发电系统的实验设计。使用网络方法和精确的分析方法确定了光伏渗透率作为其价格和化石发电机容量的函数的水平。结果发现，这两种方法在最优容量方面非常接近，而在年度系统成本方面几乎相同。
This paper evaluates the accuracy of a network economic modeling approach in designing energy systems having renewable and conventional generators. The network approach models the system as a network of processes such as demands, generators, markets, and resources. The model reaches a solution by exchanging prices and quantity information between the nodes of the system. This formulation is very flexible and takes very little time to build and modify models. This paper reports an experiment designing a system with photovoltaic and base and peak fossil generators. The level of PV penetration as a function of its price and the capacities of the fossil generators were determined using the network approach and using an exact, analytic approach. It is found that the two methods agree very closely in terms of the optimal capacities and are nearly identical in terms of annual system costs.
