In the residential sector, energy micro-generation and its intelligent management have been creating novel energy market models, considering new concepts of energy usage and distribution, in which the prosumer has an active role in the energy generation and its self-consumption. The configuration of a solar photovoltaic system integrating energy storage in Portugal is yet unclear in the technical, energetic and economic point of view. The energy management jointly with the battery operation have great influence in the system configuration’s profitability value. The present work evaluates different photovoltaic system configurations with and without batteries for the normal low voltage Portuguese consumer profile with 3.45 kVA contracted power. This study presents the systems’ cost-effectiveness, within the Portuguese legislation, which promotes and enables policies for self-generation and self-consumption. The analysis is done in three different representative locations of the country, considering distinct electric tariffs. This work shows that despite the solar photovoltaic system without electricity storage is already economically viable, its integration with storage is not in most of the assessed configurations. However, it is shown that it is already possible to find profitable PV + battery configurations, even potentially improving these positive scenarios if a good energy management strategy is considered.

在住宅领域，考虑到能源使用和分配的新概念，能源微发电及其智能管理已经创建了新颖的能源市场模型，在该模型中，生产者在能源生产及其自我消费中发挥着积极作用。从技术，精力和经济的角度来看，在葡萄牙集成了能量存储的太阳能光伏系统的配置尚不清楚。能量管理与电池操作一起对系统配置的获利价值有很大影响。本工作评估了带有或不带有电池的光伏系统的不同配置，适用于常规低电压葡萄牙消费者使用3.45 kVA合同电力的情况。这项研究根据葡萄牙法律提出了该系统的成本效益，促进并实现自我产生和自我消费的政策。考虑到不同的电价，分析是在该国的三个不同的代表地点进行的。这项工作表明，尽管没有蓄电的太阳能光伏系统在经济上已经可行，但在大多数评估配置中，其与蓄电的集成都不可行。但是，事实表明，如果考虑一种好的能源管理策略，甚至可以找到有利的PV +电池配置，甚至有可能改善这些积极的情况。这项工作表明，尽管没有蓄电的太阳能光伏系统在经济上已经可行，但在大多数评估配置中，其与蓄电的集成都不可行。但是，事实表明，如果考虑一种好的能源管理策略，甚至可以找到有利的PV +电池配置，甚至有可能改善这些积极的情况。这项工作表明，尽管没有蓄电的太阳能光伏系统在经济上已经可行，但在大多数评估配置中，其与蓄电的集成都不可行。但是，事实表明，如果考虑一种好的能源管理策略，甚至可以找到有利的PV +电池配置，甚至有可能改善这些积极的情况。
