In recent years, distributed generation resources, especially renewable energies, have utilized in different situations; to solve the environmental pollution problems and lack of sufficient energies. In this regard, microgrid’s bi-objective energy scheduling and management are considered with INVELOX wind turbine, micro-turbine, boiler, CHP, photovoltaic, wind turbines, and also energy storage systems to enhance the reliability of the network. Moreover, portable resources have been used to manage the demand side. The remarkable innovation of this paper is to control the transmission line circuit breakers, and as a result, control the ecological contamination and microgrid’s cost; by variation in exchangeable power. In this strategy, the microgrid is capable of changing the tie line capacity and achieve the top-selling or buying electricity to/from the power system by switching the circuit breakers (circuit breakers can switch by operator decision or smart devices if required, at all-time intervals). The proposed strategy is modeled as mixed-integer linear programming. All-out expense and ecological contamination of under-study’s microgrid are considered as the objective function. The EPC technique and fuzzy methodology have been used to tackle the problem and select the ideal arrangement and solution, respectively. The outcomes display the improvement of microgrid operation with the presented energy management strategy, so that cost decreased by about 48.76% and 38.6%, in the last two scenarios, respectively.

输电线路切换智能调度:考虑绿色能源和INVELOX高渗透率的多目标微电网日前能源调度优化

近年来,分布式发电资源,特别是可再生能源,利用情况不同;解决环境污染问题和能源不足问题。对此,结合INVELOX风电机组、微电机、锅炉、CHP、光伏、风电机组以及储能系统,考虑微电网的双目标能源调度和管理,提高网络的可靠性。此外,便携式资源已被用于管理需求方。本文的显着创新是控制输电线路断路器,从而控制生态污染和微电网成本;通过可交换功率的变化。在这个策略中,微电网能够通过切换断路器来改变联络线容量并实现最畅销或从电力系统购买电力(断路器可以根据需要随时切换,由操作员决定或智能设备) . 所提出的策略被建模为混合整数线性规划。以在研微电网的全部费用和生态污染为目标函数。EPC 技术和模糊方法已被用于解决问题并分别选择理想的安排和解决方案。结果表明,采用所提出的能源管理策略改善了微电网运行,使成本在后两种情况下分别降低了约 48.76% 和 38.6%。
