考虑电动汽车影响的农村家庭新能源容量优化配置方法

Optimal Configuration Method of New Energy Capacity for Rural Households Considering Impact of Electric Vehicles

针对以光伏发电为主体的农村家庭新能源系统容量优化配置问题,从用户经济效益的角度出发,提出一种将电动汽车(electric vehicle,EV)用作储能装置且考虑用户出行需求的农村家庭新能源系统全寿命周期优化配置方法。首先构建了以系统年均用能成本最小和自发自用率最大为目标的优化配置模型,并结合市场电价机制及EV的使用需求制定了新能源系统综合运营模式,然后以粒子群优化(particle swarm optimization,PSO)算法求解得到家庭新能源系统中分布式电源的最优配置容量。最后,基于河北省石家庄某典型农村家庭实际用电负荷数据和气象参数进行仿真实验,结果表明:将EV与光伏出力结合,可以有效提高系统能源利用效率,减小家庭用能成本。

For optimal configuration of the rural household new energy system with photovoltaic power generation as main source,a new life cycle optimization configuration method is proposed for rural household new energy system from the perspective of user economic benefits,which uses electric vehicles(EVs)as energy storage facilities and considers the travel demands of users.Firstly,an optimal configuration model is established with the objective of minimum annual system energy cost and maximum selfgeneration and self-use rate.And a new energy system integrated operation model is formulated based on the electricity price and the demand for electric vehicles.And then the particle swarm optimization(PSO)algorithm is applied to solve the optimal configuration capacity of distributed power in the household new energy system.Finally,simulation experiments are carried out based on actual electricity load data and meteorological parameters for typical rural households in Shijiazhuang,Hebei.Results show that the combination of electric vehicles and photovoltaic power can effectively improve the system energy efficiency and reduce the energy cost.
