i know you would have found the solution, but for the reference of others i'm providing the solution. The code has been well commented and its well understandable.

createComponent(fileName, componentName){
    let injector = ReflectiveInjector.fromResolvedProviders([], this.vcRef.parentInjector);
    // 1. Create module loader
    let loader = new SystemJsNgModuleLoader(this.compiler);
    loader.load(fileName).then((nmf:NgModuleFactory<any>)=>{
        // 2. create NgModuleRef
        let ngmRef = nmf.create(injector);
        // 3. Create component factory
        let cmpFactory = ngmRef.componentFactoryResolver.resolveComponentFactory( componentName );
        // 4. Create the component
        let componentRef = this.span.createComponent(cmpFactory,0,injector,[]);
        // 5. Init the component name field.
        componentRef.instance.name = "Some Name";
        // 6. Refresh the component area.
        componentRef.changeDetectorRef.detectChanges();
        componentRef.onDestroy(()=> {
            componentRef.changeDetectorRef.detach();
        });
    });
}

By using the above function, we could inject a module from any source. For futher please refer this.
