This paper presents an accurate and realistic estimation of reactive power capability of solar photovoltaic (PV) inverters considering ambient temperature, solar irradiance, and terminal voltage. Based on the accurate estimation of reactive power capability, a self-adaptive voltage controller is proposed to enable solar PV power plant participation in voltage control ancillary service. The proposed accurate and realistic estimation has revealed the possibility of solar PV power plant failing to comply with grid code requirements under extreme weather conditions. On the other hand, the proposed control strategy has shown significantly better effectiveness to utilise solar PV inverter capability, and provide better voltage control support service to the grid.

考虑实际寿命因素的大型太阳能光伏电站自适应电压控制

本文提出了一种考虑环境温度,太阳辐照度和端电压的准确而现实的太阳能光伏(PV)逆变器无功功率估计。基于对无功功率能力的准确估计,提出了一种自适应电压控制器,以使太阳能光伏电站参与电压控制辅助服务。拟议的准确和现实的估算表明,在极端天气条件下,太阳能光伏电站可能不符合电网法规的要求。另一方面,所提出的控制策略显示出利用太阳能光伏逆变器功能的显着更好的有效性,并为电网提供了更好的电压控制支持服务。
