【摘要】：为优化整个虚拟发电厂(virtual power plant,VPP)内部分布式发电资源(distributed energy resources,DER)的调度成本,基于VPP的多代理结构形式建立了VPP内部DER的均衡调度模型,以实时满足系统负荷需求为条件,利用模仿者动态算法处理VPP内部调度资源分配问题。通过分析不同种类DER的适应度系数与可调容量,提出多方共赢的VPP内部DER的均衡调度策略:适应度系数越小(即调用成本越低)、可调容量越大的DER参与调度的机会越多,反之越少。算例分析证明了所提模型和算法的合理性和有效性。与传统基于市场机制的VPP调度方法相比,模仿者动态算法在解决VPP内部DER调度问题方面能有效控制调度成本,同时具有简便、易拓展的特点。
[Abstract]:For the optimization of the whole virtual power plant (virtual power plant, VPP) distributed energy resources (distributed energy, resources, DER) scheduling cost, the scheduling model of VPP internal DER to establish multi agent structure based on VPP, in order to meet the real-time requirements for system load conditions, using the replicator dynamics algorithm for VPP internal resource scheduling distribution. Through the analysis of different types of DER fitness coefficient and adjustable capacity, the balanced scheduling strategy proposed a win-win situation for the VPP internal DER: the smaller the fitness coefficient (that is, the lower the cost of the call), the larger capacity adjustable DER involved in scheduling more opportunities, more or less. An example analysis proves that the proposed model and algorithm is reasonable and effective. Compared with the traditional VPP scheduling method based on market mechanism, replicator dynamics algorithm can effectively solve the VPP internal control scheduling in DER scheduling problems At the same time, it is simple and easy to expand.
