Abstract

Upcoming construction proposals for utility-scale photovoltaic plants and discussion of compensation in Nigeria raise the question of appropriate grid code requirements to support system voltage control objectives. The large geographical extent, long lines, and small number of generators in the Nigerian High Voltage System make voltage control a critical issue. This paper evaluates the effect of different power control strategies for a 100 MW solar plant, using dynamic simulation of a detailed grid model. The choice of location in North of Nigeria informs ongoing discussions, and is the first published study of this type. The effect of the strategies are compared, and recommendations are made for transmission system operators and developers to consider as they define interconnection agreements.

尼日利亚与电力传输系统连接的可再生能源发电厂的电压控制并网要求
在尼日利亚,即将提出的公用事业规模光伏电站的建设建议和对补偿的讨论提出了适当的电网规范要求以支持系统电压控制目标的问题。尼日利亚高压系统地理范围大、线路长、发电机数量少,使得电压控制成为一个关键问题。本文利用详细电网模型的动态仿真,评估了100兆瓦太阳能电站不同功率控制策略的效果。地点选择在尼日利亚北部为正在进行的讨论提供信息,这是首次发表的此类研究。比较了这些策略的效果,并提出了建议,供输电系统运营商和开发商在定义互连协议时考虑。
