Actually, it's basically Maa Ambika Shivā, the consort of Bhagawan Shiva.
Skanda Purana : Devi Bhagawata Mahatmayam : Ch5: verse 96.:
“Therefore of the Bhagavata which is dear to devi, even the great Puranas also aren’t entitled to even a part of the (greatness of the) Purana of Shodashi”.
Skanda Purana : Devi Bhagawata Mahatmayam : Ch5: verse 97.:
“(In it is narrated) The secret meaning of Gayatri, and Manidweepa is described, in which exists the Bhagavati Gita, Gita by Sridevi the daughter of himavan”.
Skanda Purana : Devi Bhagawata Mahatmayam : Ch5: verse 101-102.:
“At the end of the well of nectar in the garden of thirty three trees inside the Manidweepa, within the Chintamanigruha, charmingly remains seated Amba with a smiling face in the heart (left portion) of Parashiva – such an appearance when meditated by humans they get all types of enjoyments as well as liberation. One who is worshiped by Brahma, Rudra, Achyuta, Sakra and great sages, she is for the benefit of the world, the presiding lordess of the Manidweepa“.
So, though Srimad Devi Bhagwatam generally in the Purana talks about Mata Bhubaneswari, Sri Skanda Purana tells it as the Purana of Shodashi (Mata Maha Tripura Sundari).
Lalita Sahasranama Stotram 1:32.:
“Lalita – who out of her finger nails re-created all the ten Incarnations of Narayana (Vishnu) to destroy the Asuras slain by Him in His incarnations and now recreated magically by demon-Bhanda out of a missile of his. She again burned to death the armies of demons with the fire of the great missile maha-pashupata”.
10 Avataras of Lord Vishnu = 10 Mahavidyas.

Shrimad Dēvī Bhāgavataṃ Book 7 chapter .:on the glory of Śatākṣī.:
At this moment, came, out of the body of the Devī, the principal Śaktis (forces incarnate) Kālikā, Tāriṇī, Ṣoḍaśī, Tripurā, Bhairabī, Kamalā, Bagalā, Mātaṅgī, Tripurā Sundarī, Kāmāksī, Tulajā Devī, Jambhinī, Mohinī, Ccinnamaṣtā, and ten thousand armed Guhya Kālīs and others. Thirty-two Śaktis, sixty-four Śaktis, and then innumerable Śaktis, all armed, came out of the Devī successively.
So, according to Devi Bhagavatam, all Mahavidyas and more came out from Mata Durga during her fight with Durgamasura.
So, the concept is same as the 11 Rudras also have the same names such as Shiva, Shankara, Sthanu, etc and again those names are also applied to Bhagawan Kala Agni Rudra and So on. From whom the 11 Rudras originated.
Conclusion.: Thus, the above mentioned Mata Bhubaneswari is not the part of Dasha Mahavidyas but She is the originator of the 10 Mahavidyas and at the same time all the names can be applied to het also and she can be called by any names such as Tripura Sundari, Maha Kaki, Durga, Sati, Parvati, Bhuvaneshwari, etc etc. Basically, she is the Adi Para Shakti and Maha Vidyas are her partial incarnations.
Sri Shiva Purana 3.16, Dash Avatar (10 Incarnations of Shiva) Describes about the ten incarnations of Shiva and their corresponding power (Shakti).:
Sutji said- The first incarnation of lord Shiva was as Mahakal and his Shakti was called Mahakali. Lord Shiva took his second incarnation as Tar and his Shakti was called 'Tara'. The third incarnation of Lord Shiva was as Bhuvaneshwar and his Shakti was called 'Bhuvaneshwari'. Lord Shiva took his fourth incarnation as 'Shodash' who was also known as 'Srividdyesh' and his Shakti was called 'Shodashi' or 'Shri'. Lord Shiva took his fifth incarnation as Bhairav and his Shakti was called 'Bhairavi'. The sixth incarnation of Lord Shiva is famous as 'Chhinamastak' and his Shakti by the name of 'Chhinamasta.Lord Shiva took his seventh incarnation as 'Dhoomvan' and his Shakti was known as 'Dhoomvati. The eighth incarnation was as Baglamukh and his Shakti as Baglamukhi. The nineth incarnation of lord Shiva became famous as Matang and his Shakti as 'Matangi'. Lord Shiva took his tenth incarnation as 'Kamal' and his Shakti as Kamala. If these ten incarnation of Shiva are worshipped along with his ten Mahavidyas then a man attains salvation.
I hope this clarifies all your queries. Prd..
