For the market participants (i.e., energy consumers and prosumers) in a microgrid to acquire profits via trading surplus electricity, it is essential to determine an appropriate trading price of electricity. Therefore, this study developed a business feasibility evaluation model to predict the optimal trading price of electricity that maximizes the profits of both the market participants participating in the Peer-to-Peer (P2P) electricity trading, by reflecting the structure of electricity market in South Korea. The residential areas located in the seven metropolitan cities in South Korea (Seoul, Incheon, Daejeon, Daegu, Ulsan, Busan, and Gwangju) were selected for the model application. The main findings from the model application are as follows. First, the annual electricity generation of the solar photovoltaic (PV) panel was highest in Daegu (5,541 kWh) and lowest in Seoul (3,569 kWh). In addition, the electricity generation was generally shown to be higher in spring (March–May) and relatively lower in summer and winter. Second, the estimated annual maximum profit of the energy prosumer was highest in Daegu (US$995.5) and lowest in Seoul (US$638.1). Furthermore, it was determined to be beneficial to the energy prosumers to reduce their self-use rate to the extent possible. By using the developed business feasibility evaluation model, decision makers, including specialists and non-specialists, can determine the optimal trading price of electricity and whether to participate in the market of P2P electricity trading.

通过估算最佳交易价格开发可盈利的P2P电力交易的业务可行性评估模型

为了使微电网中的市场参与者(即,能源消费者和生产者)通过交易剩余电力获得利润,必须确定适当的电力交易价格。因此,本研究开发了一种商业可行性评估模型,通过反映南方电力市场的结构,预测可以使参与对等(P2P)电力交易的市场参与者双方的利润最大化的最佳电力交易价格。朝鲜。模型应用选择了位于韩国七个城市(首尔,仁川,大田,大邱,蔚山,釜山和光州)的居民区。该模型应用程序的主要发现如下。首先,大邱地区太阳能光伏(PV)面板的年发电量最高(5,541 kWh),首尔最低(3,569 kWh)。此外,通常显示春季(3月至5月)的发电量较高,而夏季和冬季则相对较低。其次,能源生产者的估计年度最高利润在大邱最高(995.5美元),在首尔最低(638.1美元)。此外,已确定将能量消耗者的自用率降低到可能的程度是有益的。通过使用已开发的业务可行性评估模型,决策者,包括专家和非专家,都可以确定最佳的电力交易价格以及是否参与P2P电力交易市场。通常显示,春季(3月至5月)的发电量较高,而夏季和冬季则相对较低。其次,能源生产者的估计年度最高利润在大邱最高(995.5美元),在首尔最低(638.1美元)。此外,已确定将能量消耗者的自用率降低到可能的程度是有益的。通过使用已开发的业务可行性评估模型,决策者,包括专家和非专家,都可以确定最佳的电力交易价格以及是否参与P2P电力交易市场。通常显示,春季(3月至5月)的发电量较高,而夏季和冬季则相对较低。其次,能源生产者的估计年度最高利润在大邱最高(995.5美元),在首尔最低(638.1美元)。此外,已确定将能量消耗者的自用率降低到可能的程度是有益的。通过使用已开发的业务可行性评估模型,决策者,包括专家和非专家,都可以确定最佳的电力交易价格以及是否参与P2P电力交易市场。已确定尽可能降低能源使用者的自用率是有益的。通过使用已开发的业务可行性评估模型,决策者,包括专家和非专家,都可以确定最佳的电力交易价格以及是否参与P2P电力交易市场。已确定尽可能降低能源使用者的自用率是有益的。通过使用已开发的业务可行性评估模型,决策者,包括专家和非专家,都可以确定最佳的电力交易价格以及是否参与P2P电力交易市场。
