摘要

在发展中国家,偏远地区的电气化和常规电网的扩展仍然是一项重大挑战。可再生能源和储能系统与偏远地区电网的整合和管理可以解决这一问题。本文旨在为偏远地区供电(RAPS)系统开发基于规则的智能能源管理系统(RBSEMS)范例,以同时实施源端和需求端的能源管理。不间断供电和降低用电成本是这项工作的首要目标。此外,在多目标框架中,减少对电网的依赖也是首要目标之一。远程区域电力系统控制器的建模旨在提供不同能源运行模式之间的无缝转换,并无延迟地响应 RBSEMS 信号。为验证 RBSEMS,在 MATLAB Simulink 中对由可调度和不可调度负载、太阳能光伏发电系统、风能系统、电池储能系统、公用电网及其控制器组成的 RAPS 测试系统进行了建模。对各种情况的综合分析和仿真结果表明了所提方法在建模的 RAPS 系统中的有效性。此外,还介绍了四项性能指标,以突出拟议工作的优点。在案例 2B 中,当单独考虑主要目标时,总成本降低了 11.56%。当同时考虑主要目标和次要目标时,情况 3B 的总成本降低了 3.69%,但独立性能指数从 0.7815 提高到了 0.836,这表明电网依赖性降低了。模拟的系统本地控制器的响应时间为 24.2 毫秒,对于 0.25 秒的时间间隔来说是可以接受的。

Rule based coordinated source and demand side energy management of a remote area power supply system

Rule based coordinated source and demand side energy management of a remote area power supply system

The electrification and extension of conventional grid in remote areas is still a major challenge in developing countries. This can be addressed with an integration and management of renewable energy sources and energy storage systems to the remote network. This paper aims to develop a Rule-based Smart Energy Management System (RBSEMS) paradigm for Remote area power supply (RAPS) systems to implement simultaneous source-side and demand-side energy management. The uninterrupted power supply and reduction of electricity cost is the primary objective of the work. Besides, in the multi-objective framework, reduction of dependency on the grid is considered along with the primary objective. The remote area power system controllers are modelled to provide a seamless transition between different modes of operation of energy sources and respond to RBSEMS signals without much delay. The RAPS test system consisting of schedulable and non-schedulable loads, solar PV, wind energy system, battery energy storage system, utility grid along with its controllers are modelled in MATLAB Simulink to validate the RBSEMS. The comprehensive analysis and simulation results of various cases present the effectiveness of the proposed approach on the modelled RAPS system. Four performance indices are also presented to highlight the merits of the proposed work. The overall cost is decreased by 11.56% in case 2B, when primary objective is considered alone. When primary and secondary objectives are considered together, the overall cost is decreased by 3.69% in case 3B but the independent performance index is improved from 0.7815 to 0.836 indicating the reduced grid dependency. The response time of the modelled local controllers of the system is found to be 24.2 ms, which is acceptable for an interval of 0.25 s.
