摘要: |
工业光伏微电网配置储能时需考虑其负荷特性,在保证供电可靠性的前提下最大化提升光伏利用率。在详细分析工业重要负荷的运行特性和启动冲击特性基础上,结合工业分时电价机制,给出了适合工业微电网的储能系统充放电策略。进而以光伏利用率最大和年净利润最大为目标,构建了工业光伏微电网的储能容量优化配置的多目标优化模型,并采用NSGA-II算法对所建模型进行求解。将优化方法应用于广东某实际工业光伏微电网中,结果表明经过优化的储能系统可在离网情况下保证系统中重要负荷的稳定运行,在并网运行时促进光伏的就地消纳。 |

Abstract: |
The load characteristics should be considered in allocation of energy storage for industrial PV microgrid. The purposes of the allocation are ensuring the reliability of power supply and improving the photovoltaic utilization. The paper analyzes the operating characteristics and the impact of starting feature of industry sensitive loads in the PV microgrid for industries. In this paper, energy storage system charging and discharging control strategy based on industry time of use electricity price (TOU) mechanism which is applicable to industrial PV microgrid is proposed. Based on the analysis of main issues of the problem, a multi-objective optimization model is proposed and optimization approach based on NSGA-II algorithm is presented to search the optimal solution. The proposed operating strategy and optimization method are then tested on a Guangdong photovoltaic micro-grid. Results demonstrate that the optimized storage system can meet the requirement of expectation of system uptime under extreme conditions when operate autonomously and improve the PV power consumption rate while interconnect to the grid. |
