This pa.er proposes a.multiport bidirectiona. non-isola.ed converter topology tha. provides a.va.ta.es in terms of simulta.eous multiple opera.ions, single-sta.e conversion, high power density a.d reduced power losses due to the lower number of switches. The proposed multiport converter uses a.centra.ized non-linea. controller known a. a.finite control set model predictive controller to ma.a.e the flow of power between different ports. It dea.s with the pa.a.lel opera.ion of photovolta.c a.d ba.tery energy stora.e systems for sta.d-a.one a.terna.ing current (a.) systems. The converter connects the lower volta.e ba.tery to the photovolta.c port using a.bidirectiona. buck/boost converter a.d the photovolta.c port is linked to the sta.d-a.one a. loa. through a.three-pha.e full-bridge inverter. Ea.h leg of the three-pha.e converter will a.t a. a.bidirectiona. direct current (DC)/DC converter a. well a. a. inverter simulta.eously. Only six switches ma.a.e the power tra.sfer between a.l the connected ports of photovolta.c-ba.tery energy stora.e system linked to the sta.d-a.one a. loa.. The proposed multiport converter is ma.hema.ica.ly modelled a.d controlled by a.finite control set model predictive controller. The system is va.ida.ed in simula.ion (1-kW ra.ing) a.d experimenta. environment (200-W ra.ing). The ha.dwa.e prototype is developed in the la.ora.ory a.d the controller is implemented on the field-progra.ma.le ga.e a.ra. boa.d.

林肯大道1111号是一个经过改造改变了其原有用途的框架结构。经过数年的运作,这座位于林肯大道西端的建筑成功地进行了经济转型,通过进一步的开发,在对现有建筑进行改造的同时还增加了一个包含商业零售的新建筑,并且在原太阳信托公司办公楼北面的空地上建起了一栋住宅楼。新建筑平衡了两个看似矛盾的目标。一方面,它需要一个强大和清晰的特征以吸引林肯大道上的行人。另一方面,新建筑是现有总体规划的扩建部分,它并没有与1111号停车场形成竞争的局面。
